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

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.
v8-v9 Changed dev_printk to dev_err since all log levels are KERN_ERR.

Applied v10 series and put it into my "next" branch so linux-next will
grab it on the next cycle.  Will try to interest the "tip" maintainers in
pulling again in a few days.
