Mateusz Guzik 736ff8c396 hwpmc: partially depessimize munmap handling if the module is not loaded
HWPMC_HOOKS is enabled in GENERIC and triggers some work avoidable in the
common (module not loaded) case.

In particular this avoids permission checks + lock downgrade
singlethreaded and in cases were an executable mapping is found the pmc
sx lock is no longer bounced.

Note this is a band aid.
