Subject: [PATCH] NFS: Refactor mount option address parsing into separate
 function

Refactor the logic to parse incoming text-based IP addresses.  Use the
in4_pton() function instead of the older in_aton(), following the lead
of the in-kernel CIFS client.

Later we'll add IPv6 address parsing using the matching in6_pton()
function.  For now we can't allow IPv6 address parsing: we must expand
the size of the address storage fields in the nfs_parsed_mount_options
struct before we can parse and store IPv6 addresses.
