NLM: Fix GRANT callback address comparison when IPv6 is enabled
The NFS mount command may pass an AF_INET server address to lockd. If lockd happens to be using a PF_INET6 listener, the nlm_cmp_addr() in nlmclnt_grant() will fail to match requests from that host because they will all have a mapped IPv4 AF_INET6 address. Adopt the same solution used in nfs_sockaddr_match_ipaddr() for NFSv4 callbacks: if either address is AF_INET, map it to an AF_INET6 address before doing the comparison.
