From: Daniel Jurgens <danielj@xxxxxxxxxxxx>
ib_get_cached_subnet_prefix can technically fail, but the only way it
could is not possible based on the loop conditions. Check the return
value before using the variable sp to resolve a static analysis warning.
Fixes: 8f408ab64be6 ("selinux lsm IB/core: Implement LSM notification
system")
