netfilter: nf_tables: fix out of memory error handling

[ Upstream commit 5e1be4cdc98c989d5387ce94ff15b5ad06a5b681 ]

Several instances of pipapo_resize() don't propagate allocation failures,
this causes a crash when fault injection is enabled for gfp_kernel slabs.

Fixes: 3c4287f62044 ("nf_tables: Add set type for arbitrary concatenation of ranges")
