vdpa/mlx5: Fix incorrect error code reporting in query_virtqueues

When query_virtqueues() fails, the error log prints the variable err
instead of cmd->err. Since err may still be zero at this point, the
log message can misleadingly report a success value 0 even though the
command actually failed.

Even worse, once err is set to the first failure, subsequent logs
print that same stale value. This makes the error reporting appear
one step behind the actual failing queue index, which is confusing
and misleading.

Fix the log to report cmd->err, which reflects the real failure code
returned by the firmware.
