Subject: [PATCH 24/34] libacl: acl_set_file: Remove unnecesary racy check

Only directories can have default acls.  This is checked in the kernel, and
unnecessarily also in acl_set_file. There is a window between checking the file
type and setting the acl, so the check in acl_set_file isn't even safe.  Remove
it.
