[PATCH 5.10 516/663] drm/amdkfd: Fix recursive lock warnings

[Greg Kroah-Hartman]

From: Felix Kuehling <felix.kuehl...@amd.com>

commit 1fb8b1fc4dd1035a264c81d15d41f05884cc8058 upstream.

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")
