5.10-stable review patch. If anyone has any objections, please let me know.

From: Pablo Neira Ayuso pablo@netfilter.org
commit 6d365eabce3c018a80f6e0379b17df2abb17405e upstream.
nft_trans_gc_queue_sync() enqueues the GC transaction and it allocates a new one. If this allocation fails, then stop this GC sync run and retry later.
