968a5ae89f smbd: directly pass fsp to SMB_VFS_FGETXATTR() in fget_ea_dos_attribute()
We're now consistently passing the base_fsp to SMB_VFS_FSET_DOS_ATTRIBUTES(), so
we don't need to check for a stream_fsp here anymore.

Additionally vfs_default will assert a non-stream fsp inside
vfswrap_fgetxattr(), so in case any caller wrongly passes a stream fsp, this is
caught in vfs_default.

Commit d71ef1365cdde47aeb3465699181656b0655fa04 caused a regression where the
creation date on streams wasn't updated anymore on the stream fsp.

By adding a simple wrapper vfs_fget_dos_attributes() that takes care of

- passing only the base_fsp to the VFS, so the VFS can be completely agnostic of
  all the streams related complexity like fake fds,

- propagating any updated btime from the base_fsp->fsp_name to the
  stream_fsp->fsp_name

643da37fd1 smbd: remove itime and file_id logic and code
This bases File-Ids on the inode numbers again. The whole stuff was
added because at that time Apple clients

1. would be upset by inode number reusage and

2. had a client side bug in their fallback implemetentation that
assigns File-Ids on the client side in case the server provides
File-Ids of 0.

After discussion with folks at Apple it should be safe these days to
rely on the Mac to generate its own File-Ids and let Samba return 0
File-Ids.

469a7ebf76 smbd: Simplify dos_mode_check_compressed()
btrfs_fget_compression() is the only real implementation of
VFS_GET_COMPRESSION. It does not use the mem_ctx argument, so it seems
unnecessary to do a full malloc()/free() cycle here. Moreover, if this
was actually required, talloc_stackframe() would be more appropriate
these days as deep within the smbd even loop it does not go through
the libc malloc, but just increments a pointer.

97caec07ff smbd: also check for NT_STATUS_NOT_SUPPORTED
If a VFS module fails SMB_VFS_GETXATTRAT_SEND/RECV with ENOSYS like currently
vfs_shadow_copy2 or any other module that uses
vfs_not_implemented_getxattrat_send() the ENOSYS error that
vfs_not_implemented_getxattrat_send() sets gets mapped to
NT_STATUS_NOT_SUPPORTED by map_nt_error_from_unix().

Unfortunately when checking whether the async SMB_VFS_GETXATTRAT_SEND() failed
and to determine if the sync fallback should be triggered, we currently only
check for NT_STATUS_NOT_IMPLEMENTED which is the error we get when "store dos
attributes" is disabled.
