[ Upstream commit c88baabf16d1ef74ab8832de9761226406af5507 ]
revert commit 4c905f6740a3 ("netfilter: nf_tables: initialize registers in nft_do_chain()").
Previous patch makes sure that loads from uninitialized registers are detected from the control plane. in this case rule blob auto-zeroes registers. Thus the explicit zeroing is not needed anymore.
