mount: ignore unknown mount options when remounting NFS mounts
Don't fail on unknown nfs mount options. The kernel automatically
adds a few mount options that we don't currently handle, like:
sec=null|sys|krb5..
mountaddr=<ip>
mountproto=tcp|udp
local_lock=none|all|flock|posix
Which causes a simple mount -o remount,rw <mountpoint> to fail.
