nfs: only show Posix ACLs in listxattr if actually present
commit
74adf83f5d7720925499b4938f930591f947b660 upstream.
The big ACL switched nfs to use generic_listxattr, which calls all existing
->list handlers. Add a custom .listxattr implementation that only lists
the ACLs if they actually are present on the given inode.
