nb/intel/ironlake/raminit: Work around compiler bug

This fixes commit e1d1fe454cf27d6b1c2ef5625f1cefc1a9c6ec9d
initialize 'reply.command'.

The compiler now optimized away the final condition, that checks
the result of heci message, resulting in a binary that always
calls die().

Fix that behaviour by using volatile.
Tested on Lenovo T410: Boots again into Linux.
