iwlwifi: fix TX status for aggregated packets
Only the first packet is currently handled correctly, but then all others are assumed to have failed which is problematic. Fix this, marking them all successful instead (since if they're not then the firmware will have transmitted them as single frames.) This fixes the lost packet reporting. Also do a tiny variable scoping cleanup.
