drm/amdkfd: Fix recursive lock warnings

memalloc_nofs_save/restore are no longer sufficient to prevent recursive
lock warnings when holding locks that can be taken in MMU notifiers. Use
memalloc_noreclaim_save/restore instead.

Fixes: f920e413ff9c ("mm: track mmu notifiers in fs_reclaim_acquire/release")
