iwlwifi: pcie: simplify MSI-X cause mapping

Browse source

We're currently manually encoding a calculation here since the HW
just maps all the bits of specific registers to specific offsets,
which led to the bug fixed here previously with the Bz SW_ERROR
interrupt.

Clean up the code to only know about the mapping offset (-16 or
16 depending on the register) to avoid such issues in the future.
