When inherting permissions on the created stream, we call into the VFS to fetch
the streams security descriptor via inherit_access_posix_acl() ->
copy_access_posix_acl() -> SMB_VFS_SYS_ACL_SET_FD() passing the stream fsp which
triggers the assert SMB_ASSERT(!fsp_is_alternate_stream(fsp)) in
vfswrap_sys_acl_set_fd() in vfs_default.
Just passing the base fsp to the VFS fixes this.
vfs_streams_depot which *does use* distinct backend filesystem files for the
streams, currently does not apply permissions to the stream files at all, so the
incomplete behaviour of vfs_streams_depot is not affected by this change.
If in the future someone want to fix this defficiency in vfs_streams_depot, the
module code can use fsp->stream_fsp to base decisions in VFS ops whether the
module should carry out some action.
