[PATCH v7 3/3] aerdrv: Cleanup log output for CPER based AER

From: Lance Ortiz
Date: Tue Dec 04 2012 - 16:08:20 EST

These changes make cper_print_aer more consistent with aer_print_error
which is called in the AER interrupt case. The string in the variable
'prefix' is printed at the beginning of each print statement in
cper_print_aer(). The prefix is a string containing the driver name
and the device's slot location. From the callers the value of prefix
is never assigned and is NULL, so when cper_print_aer prints data the
initial string does not get printed. This string is important because
it identifies the device that the error is on.

v1-v2 fix some compile errors withinn the #ifdef
v3-v4 remove agent id stuff and kept print the same to avoid
compatibility issues
