[PATCH 3/6][SRU][Focal] iwlwifi: pcie: rx: use rxq queue_size instead of constant

[AceLan Kao]

From: Johannes Berg <johannes.berg at intel.com>

BugLink: https://bugs.launchpad.net/bugs/1865962

This is a little less efficient now as it's known to be a
multiqueue device in this function, but a future patch will
have to use a variable here anyway, so use rxq->queue_size
now instead to make it clearer.
