x86: Work around compilation warning in arch/x86/kernel/apm_32.c
The following fix was initially inspired by David Howells fix
few days back:
http://lkml.org/lkml/2009/7/9/109
However, Ingo disapproves such fixes as it's dangerous (it can
hide future, relevant warnings) - in something as
performance-uncritical.
So, initialize 'err' to '0' to work around a GCC false positive
warning:
