ANDROID: dma-buf: system_heap: kmap_local_page instead of kmap_atomic

Browse Source 
kmap_atomic was deprecated in 5.11, and checkpatch now warns about use
of it. Replace with kmap_local_page, and do not manually disable
preemption or page faults.

Bug: 264474028
Fixes: ef2ab77cc1 ("ANDROID: dma-buf: system_heap: Add pagepool support to system heap")
