patch to correct alignment

Mea maxima culpa.  I overlooked the issue of old liblustre versions.  This
patch
handles it.

updated patch

This patch update ensures a NAK is sent on any protocol version difference, not

just to newer peers.  This will ensure old liblustre peers print the protocol
version error message, but please note they will still hang/timeout.

This patch update also makes liblustre clients abort if they are explicitly
NAKed (i.e. the server rejected the protocol version) although this can be
disabled by default (PTLLND_ABORT_ON_NAK=0 in the process environment). 
However
this will obviously not change the behaviour of "old" liblustre
clients.
