The SIE instruction is interruptible, so instead of having a guest

This patch series fixes a number of of KVM/ARM issues that have either
been spotted during the review of the arm64 code, or while reworking

Only the first patch fixes a potential (if unlikely) problem, the
others are either cosmetic or performance related.
Tested on TC-2.

Currently, vhost-net and vhost-scsi are sharing the vhost core code.
However, vhost-scsi shares the code by including the vhost.c file
directly.
Making vhost a separate module makes it is easier to share code with
other vhost devices.
