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. Signed-off-by: "J.
