device-assignment: Byte-wise ROM read
The host kernel filters the PCI option ROM, returning only bytes for
the actual ROM size, not for the whole BAR. That means we typically
do a short read of the PCI sysfs ROM file. Read it a byte at a time
so we know how much to actually copy and only skip the copy if we
get nothing.
