Btrfs: setup a nofs context for memory allocation at __btrfs_set_acl
commit a0873490660246db587849a9e172f2b7b21fa88a upstream.
We are holding a transaction handle when setting an acl, therefore we can
not allocate the xattr value buffer using GFP_KERNEL, as we could deadlock
if reclaim is triggered by the allocation, therefore setup a nofs context.
Fixes: 39a27ec1004e8 ("btrfs: use GFP_KERNEL for xattr and acl allocations")
