wifi: iwlwifi: don't warn during reprobe

[ Upstream commit 696cca64308dc641d0bbe4aa2c09dd9752aa288d ]

During reprobe, the sw state is being destroyd, and so is the
connection. When the peer STA is being removed, the opmode sends a
command to flush the TXQs of the STA and uses iwl_trans_wait_txq_empty.

This one warns if the FW is not alive, but it really shouldn't if
there is a FW error - and return silently instead, just like we do when
sending a hcmd.
