This also converts the special msm_gem_get_vaddr_active() to expect the
lock to already be held. There are two call-sites for this, one already
has the lock held, so it is more straightforward to just open-code the
locking for the other caller.

Unfortunately, due to an dev_pm_opp locking interaction with
mm->mmap_sem, we need to do pm get before aquiring obj locks,
otherwise we can have anger lockdep with the chain:
opp_table_lock --> &mm->mmap_sem --> reservation_ww_class_mutex
For an explicit fencing userspace, the impact should be minimal
as we do all the fence waits before this point. It could result
in some needless resumes in error cases, etc.
