It seems there is no need to keep the inuse field signed and end up with
compiler warnings for sign-compare.
CC libvduse.o
libvduse.c: In function ‘vduse_queue_pop’:
libvduse.c:789:19: error: comparison of integer expressions of different
signedness: ‘int’ and ‘unsigned int’ [-Werror=sign-compare]
789 | if (vq->inuse >= vq->vring.num) {
| ^~
Instead of casting the comparison to unsigned int, just make the inuse
field unsigned int in the fist place.
