drm/amdkfd: Use non-atomic bitmap functions when possible
All uses of the 'kfd->gtt_sa_bitmap' bitmap are protected with the
'kfd->gtt_sa_lock' mutex.
So:
- prefer the non-atomic '__set_bit()' function
- use the non-atomic 'bitmap_[set|clear]()' functions instead of
equivalent 'for' loops. These functions can work on several bits at a
time
