iwlwifi: trans: support a callback for ASYNC commands
This allows the op_mode to request from the transport to call a callback when an ASYNC commands is completed by the firmware. The same callback will be called for all the commands. Pass the command whose response triggers the callback as a parameter to the callback itself. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
