iwlwifi: fix potential lock inversion deadlock
This is a change to a previous patch ("iwlwifi: 3945 split tx_complete
to command and packet function") to ensure we do not have hardirq safe
locks (priv->lock in this case) depend on hardirq unsafe locks.
We only call iwl3945_tx_queue_reclaim while in a tasklet so we have to use
the irqsafe version of the function.
