PCI/AER: Simplify AER_RECOVER_RING_SIZE definition
ACPI Platform Error Interfaces (APEI) convey error information to the OS.
If the APEI GHES driver receives information about PCI errors, it queues it
in aer_recover_ring for processing by the PCI AER code.
AER_RECOVER_RING_SIZE is the size of the aer_recover_ring FIFO and is
arbitrary, with no direct connection to hardware.
AER_RECOVER_RING_ORDER was only used to compute AER_RECOVER_RING_SIZE.
Remove it and define AER_RECOVER_RING_SIZE directly. No functional change
intended.
