UPSTREAM: mm/damon/vaddr: call damon_update_region_access_rate() always

When getting mm_struct of the monitoring target process fails, there wil
be no need to increase the access rate counter (nr_accesses) of the
regions for the process.  Hence, damon_va_check_accesses() skips calling
damon_update_region_access_rate() in the case.  This breaks the assumption
that damon_update_region_access_rate() is called for every region, for
every sampling interval.  Call the function for every region even in the
case.  This might increase the overhead in some cases, but such case would
not be frequent, so no significant impact is really expected.
