Subject: iwlwifi: mvm: rs: fix mimo delimiter in LQ cmd
From: Eyal Shapira <eyal@xxxxxxxxxx>
commit d9088f60425e0acd8a8f05fdfcfdd288d3258641 upstream.
mimo_delim was always set to 0 instead of pointing to
the first SISO entry after MIMO rates.
This can cause keep transmitting in MIMO even when we shouldn't.
For example when the peer is requesting static SMPS.
