Add a sanity check for the existence of an "addr" option
to both NFS clients. This avoids the crash reported by
Sergey Kandaurov (pluknet@gmail.com) to the freebsd-fs@
list with subject "[old nfsclient] different nmount()
args passed from mount vs mount_nfs" dated May 17, 2011.
Tested by: pluknet at gmail.com (old nfs client)
MFC after: 2 weeks
