amdgpu: Use uint32_t i in amdgpu_find_bo_by_cpu_mapping

The compiler points out that an int doesn't work as intended if
dev->bo_handles.max_key > INT_MAX:

../../amdgpu/amdgpu_bo.c: In function ‘amdgpu_find_bo_by_cpu_mapping’:
../../amdgpu/amdgpu_bo.c:550:16: warning: comparison of integer expressions of different signedness: ‘int’ and ‘uint32_t’ {aka ‘unsigned int’} [-Wsign-compare]
  for (i = 0; i < dev->bo_handles.max_key; i++) {
                ^
../../amdgpu/amdgpu_bo.c:558:8: warning: comparison of integer expressions of different signedness: ‘int’ and ‘uint32_t’ {aka ‘unsigned int’} [-Wsign-compare]
  if (i < dev->bo_handles.max_key) {
        ^
