drm/amdkfd: Use bitmap_zalloc() when applicable
'doorbell_bitmap' and 'queue_slot_bitmap' are bitmaps. So use
'bitmap_zalloc()' to simplify code, improve the semantic and avoid some
open-coded arithmetic in allocator arguments.
Also change the corresponding 'kfree()' into 'bitmap_free()' to keep
consistency.
