By factoring out recursive_rmdir_fsp() we can do the recursion using
openat_pathref_fsp_lcomp(). This makes strace for a recursive
directory removal look a *lot* cleaner.

I'm not sure, but it might be that we don't have a full fd coming into
can_delete_directory_fsp() without O_PATH. We open a real fd for
readdir() in all cases, which we can use for sure in openat &
friends. Use that as dirfsp for openat.

strace gives a clue: samba try to remove 'file.txt' in the dst folder but
actually it is not existed yet, and got an errno = ENOENT,
renameat(32, "file.txt", 31, "file.txt") = -1 EXDEV (Invalid cross-device link)
unlinkat(31, "file.txt", 0) = -1 ENOENT (No such file or directory)
Commit 5c18f074be ("s3: VFS: crossrename. Use real dirfsp for
SMB_VFS_RENAMEAT()") seems unintentionally removed errno ENOENT checking,
so add it back could address 1st issue.

We need to detach dcesrv_iface_state from dcesrv_assoc_group,
if dcesrv_assoc_group is free'ed first.
Typically this doesn't happen, but it does when
rpc_worker_connection_terminated explicitly calls
talloc_unlink(conn, conn->assoc_group)
and dcesrv_iface_state_store_conn() is used.
But we better do it in all assoc_group destructors.
