libvhost-user: Use unsigned int i for some for-loop iterations 

The sign-compare warning also hits some of the for-loops, but it easy
fixed by just making the iterator variable unsigned int.

  CC       libvhost-user.o
libvhost-user.c: In function ‘vu_gpa_to_va’:
libvhost-user.c:223:19: error: comparison of integer expressions of different signedness: ‘int’ and ‘uint32_t’ {aka ‘unsigned int’} [-Werror=sign-compare]
  223 |     for (i = 0; i < dev->nregions; i++) {
      |                   ^
