hw/xen: do not set is_external=true on evtchn fds
is_external=true suspends fd handlers between aio_disable_external() and
aio_enable_external(). The block layer's drain operation uses this
mechanism to prevent new I/O from sneaking in between
bdrv_drained_begin() and bdrv_drained_end().
The previous commit converted the xen-block device to use BlockDevOps
.drained_begin/end() callbacks. It no longer relies on is_external=true
so it is safe to pass is_external=false.
This is part of ongoing work to remove the aio_disable_external() API.
