[PATCH 15/18] smartpqi: fix BUILD_BUG_ON() statements

[Don Brace <don.brace@xxxxxxxxxxxxx>]

From: Mike McGowen <Mike.McGowen@xxxxxxxxxxxxx>

Add calls to the functions at the beginning driver initialization.

The BUILD_BUG_ON() statements that are currently in functions named
verify_structures() in the modules smartpqi_init.c and smartpqi_sis.c
do not work as currently implemented.
