MdeModulePkg/PciBus: Fix system hang when no PCI Option ROM exists
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1394
When there is no PCI option ROM exists, today's logic still creates
virtual BAR for option ROM using Length = 0, Alignment = (-1).
It causes the final MEM32 alignment requirement is as big as
0xFFFFFFFF_FFFFFFFF.
The patch fixes this issue by only creating virtual BAR for option
ROM when there is PCI option ROM.
