smb/client: return EOPNOTSUPP for unsupported O_TMPFILE
Some SMB servers return STATUS_OBJECT_NAME_NOT_FOUND or
STATUS_DELETE_PENDING when creating an O_TMPFILE.
The SMB client maps them to ENOENT.
The ENOENT error is supposed to be returned when the path
(a target directory in this case) does not exist, while a
lack of support of O_TMPFILE by the target file system should
be indicated by EOPNOTSUPP.
