Fix alignment for CONFIG_IA64_SGI

The _con.... variables happened to be placed on a 4 byte
boundary in some compiles for CONFIG_IA64_SGI. Wasted some time
chasing ghosts in functions that were never executed but modifications
to these function would oops the system. Make sure that
this does not happen again by moving the alignment operation for
IA64_GENERIC out of the #ifdef.
