iwlwifi: do not nulify ctx->vif on reset

commit 8db4c7e25d153fb049e81715d72fa3be3a0c3b69 upstream.

ctx->vif is dereferenced in different part of iwlwifi code, so do not
nullify it.

This should address at least one of the possible reasons of WARNING at
iwlagn_mac_remove_interface, and perhaps some random crashes when
firmware reset is performed.
