Emmanuel Grumbach 5a12a07e44 iwlwifi: dvm: fix flush support for old firmware
Since the commit below, iwldvm sends the FLUSH command to
the firmware. All the devices that use iwldvm have a
firmware that expects the _v3 version of this command,
besides 5150.
5150's latest available firmware still expects a _v2 version
of the FLUSH command.
This means that since the commit below, we had a mismatch for
this specific device only.
This mismatch led to the NMI below:
