df7efdf046 s3: smbd: Cleanup - Make rmdir_internals() use NTSTATUS internally without depending on errno.
As we already need to return NTSTATUS, map errno to NTSTATUS directly at point of failure
and don't depend on keeping it around. No change in client-visible behavior but makes
rmdir_internals() easier to understand (for me at least).

e91b59c4df smbd: Introduce close_file_smb()
This does almost everything that close_file_free() does, but it leaves
the fsp around.

A normal close_file() now calls fsp_unbind_smb() twice. Functionally
this is not a problem, fsp_unbind_smb() is idempotent. The only
potential performance penalty might come from the loops in
remove_smb2_chained_fsp(), but those only are potentially large with
deeply queued smb2 requests. If that turns out to be a problem, we'll
cope with it later. The alternative would be to split up file_free()
into even more routines and make it more difficult to figure out which
of the "rundown/unbind/free" routines to call in any particular
situation.
