[PATCH 5.15 171/230] xfs: remove incorrect ASSERT in xfs_rename

[Greg Kroah-Hartman]

From: Eric Sandeen <sandeen@xxxxxxxxxx>

commit e445976537ad139162980bee015b7364e5b64fff upstream.

This ASSERT in xfs_rename is a) incorrect, because
(RENAME_WHITEOUT|RENAME_NOREPLACE) is a valid combination, and
b) unnecessary, because actual invalid flag combinations are already
handled at the vfs level in do_renameat2() before we get called.
So, remove it.
