[PATCH v8 3/3] aerdrv: Cleanup log output for AER

Lance Ortiz
2013-01-02T22:32:43Z

These changes make cper_print_aer more consistent with aer_print_error
and clean things up by elimiating the use of the prefix variable and
replacing it with dev_printk.

v1-v2 fix some compile errors withinn the #ifdef
v3-v4 remove agent id stuff and kept print the same to avoid
compatibility issues
v7-v8 Updated to use dev_printk instated of prefix. Changed
log levels to KERN_ERR as per Mauro's suggestion.
