In QEMU's main_loop() we used to check whether we should do a nonblocking call to main_loop(); this was deleted in commit e330c118f2a5, because now that vCPUs always drop the I/O thread lock it is an unnecessary optimization. The loop in test-char.c copied the old QEMU main_loop() code, but here the nonblocking check has never been necessary because this standalone test case doesn't hold the I/O lock anyway. Remove it, so we can drop the main_loop_wait() return value.
