OMAP: PM: SmartReflex: Fix possible null pointer read access 

These errors were found by cppcheck:
arch/arm/mach-omap2/smartreflex.c:784: error: Possible null pointer dereference: sr_info
arch/arm/mach-omap2/smartreflex.c:799: error: Possible null pointer dereference: sr_info

Both conditional statements are executed when sr_info == NULL,
so accessing sr_info->voltdm would fail.
