#1291605 — [POWERPC] bootwrapper: One check less in fsl_get_immr() after error detection

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Mon, 14 Dec 2015 23:01:32 +0100

A status check was performed by the fsl_get_immr() function even if it
was known already that a system setting did not fit to the expectations.

This implementation detail could be improved by an adjustment for
a jump label according to the Linux coding style convention.

What is the actual problem you're trying to solve?  Cluttering the code to
micro-optimize an error path is not an improvement.
