drm/i915/gvt: ensure -ve return value is handled correctly
An earlier fix changed the return type from find_bb_size however the
integer return is being assigned to a unsigned int so the -ve error
check will never be detected. Make bb_size an int to fix this.
Detected by CoverityScan CID#1456886 ("Unsigned compared against 0")
