NFSv3: Fix another acl regression
commit f87d928f6d98644d39809a013a22f981d39017cf upstream.
When creating a new object on the NFS server, we should not be sending
posix setacl requests unless the preceding posix_acl_create returned a
non-trivial acl. Doing so, causes Solaris servers in particular to
return an EINVAL.
Fixes: 013cdf1088d72 (nfs: use generic posix ACL infrastructure,,,)
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1132786
