Michael Brown 1137fa3268 [romprefix] Do not clobber stack segment when returning to BIOS 
Commit c429bf0 ("[romprefix] Store boot bus:dev.fn address as autoboot
device location") introduced a regression by using register %cx to
temporarily hold the PCI bus:dev.fn address, despite the fact that %cx
was already being used to hold the stored BIOS stack segment.
Consequently, when returning to the BIOS after a failed or cancelled
boot attempt, iPXE would end up calling INT 18 with the stack segment
set equal to the PCI bus:dev.fn address.  Writing to essentially
random areas of memory tends to upset even the more robust BIOSes.

Fix by using register %ax to temporarily hold the PCI bus:dev.fn
address.
