knfsd: nfsd4: fix handling of acl errrors
nfs4_acl_nfsv4_to_posix() returns an error and returns any posix acls
calculated in two caller-provided pointers. It was setting these pointers to
-errno in some error cases, resulting in nfsd4_set_nfs4_acl() calling
posix_acl_release() with a -errno as an argument.
Fix both the caller and the callee, by modifying nfsd4_set_nfs4_acl() to
stop relying on the passed-in-pointers being left as NULL in the error
case, and by modifying nfs4_acl_nfsv4_to_posix() to stop returning
garbage in those pointers.
Thanks to Alex Soule for reporting the bug.
