Subject: iwlwifi: don't WARN on host commands sent when firmware is dead
From: Emmanuel Grumbach <emmanuel.grumbach@xxxxxxxxx>
commit 8ca95995e64f5d270889badb3e449dca91106a2b upstream.
This triggers automatic bug reports and add no valuable
information. Print a simple error instead and drop the
host command.
