[PATCH 04/16] x86/microcode/AMD: Clean up find_equiv_id()

[Borislav Petkov]

From: Borislav Petkov <bp@xxxxxxx>

No need to have it marked "inline" - let gcc decide. Also, shorten the
argument name and simplify while-test.

While at it, make it into a proper for-loop and simplify it even more,
as tglx suggests.

No functionality change.
