intel_error_decode: Whitespacing fix

The rest of igt has moved to kernel coding style. People had already
been not conforming with the existing formatting in error decode, so we
may as well fix it.

This addresses two primary issues, tabbing (remove spaces), and space
after function in function call. I may have missed some of the latter
since that was done by hand.

I have upcoming work in this file, and it was annoying me.

v2: Fix case alignment (Chris)
