Now that the transaction context uses memalloc_nofs_save and all allocations within the this context inherit GFP_NOFS automatically, there is no reason to mark specific allocations explicitly. This patch should not introduce any functional change. The main point of this change is to reduce explicit GFP_NOFS usage inside ext4 code to make the review of the remaining usage easier.
