6.12-stable review patch. If anyone has any objections, please let me know.

From: David Howells <dhowells@xxxxxxxxxx>
[ Upstream commit b49194da2aff2c879dec9c59ef8dec0f2b0809ef ]
AFS servers pass back a code indicating EEXIST when they're asked to remove
a directory that is not empty rather than ENOTEMPTY because not all the
systems that an AFS server can run on have the latter error available and
AFS preexisted the addition of that error in general.
Fix afs_rmdir() to translate EEXIST to ENOTEMPTY.
Fixes: 260a980317da ("[AFS]: Add "directory write" support.")
