iwlwifi: mvm: compare full command ID

When comparing command IDs, the group should be taken
into account so the same command/notification from a
different group doesn't trigger anything unexpected.
Fix this by comparing to the wide ID.

Fixes: commit 1738d60b ("iwlwifi: mvm: handle RX MPDUs separately")
