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 path.  Looking up the call path, 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. This patch adds code to
create the prefix and print it in the cper_print_aer function. This
patch also calculates the device's agent id so it can be printed.
