The function aer_hest_parse() is called to determine if the given
PCI device is firmware first or not. The code loops through each
section of the HEST table to look for a match. The bug is that
the function always returns whether the last HEST section is firmware
first. The fix stops the iteration once the info.firmware_first
variable is set. This is similar to how the function aer_hest_parse_aff()
stops the iteration.
