netfilter: nf_tables: don't initialize registers in nft_do_chain()

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.
