Fails on `mkinitcpio` returning 1 when missing firmware warning is shown, despite the image generation being successful

[p0358]

Take a look:

The situation is a bit troublesome, because firmware for aic94xx is only in AUR, so cannot be added as additional package (I had one more firmware missing, but that one was fixed by adding linux-firmware-qlogic), and I don't think there's an easy way to add AUR packages with this script. At the same time these warnings are perfectly fine to ignore, and the output even ends with Image generation successful, yet the whole script exits and fails.

I did the dirty workaround below: and can confirm it fixed my issue, and the installer carried on (and the system installed and boots)
