libvhost-user: Switch to unsigned int for inuse field in struct VuVirtq

Browse Source 
It seems there is no need to keep the inuse field signed and end up with
compiler warnings for sign-compare.

  CC       libvhost-user.o
libvhost-user.c: In function ‘vu_queue_pop’:
libvhost-user.c:2763:19: error: comparison of integer expressions of different signedness: ‘int’ and ‘unsigned int’ [-Werror=sign-compare]
 2763 |     if (vq->inuse >= vq->vring.num) {
      |                   ^~
libvhost-user.c: In function ‘vu_queue_rewind’:
libvhost-user.c:2808:13: error: comparison of integer expressions of different signedness: ‘unsigned int’ and ‘int’ [-Werror=sign-compare]
 2808 |     if (num > vq->inuse) {
      |             ^

Instead of casting the comparision to unsigned int, just make the inuse
field unsigned int in the fist place.
