[Xen-devel] [PATCH] ioemu-remote&ioemu: fix libpci error handling.

[Yuji Shimada <shimada-yxb@xxxxxxxxxxxxxxx>]

This patch fixes libpci error handling.
It can be applied to both ioemu-remote and ioemu.

libpci returns ALL F when error occurs. Currently, if libpci returns ALL
F, emulation stops. But it is possible that the field of real register
which is read by guest software is ALL F.

After applying this patch, if libpci returns ALL F, ioemu will log
warning message and continue the emulation.
