bdevperf: Change g_run_failed to g_run_rc and use it correctly

Browse Source 
Change bool g_run_failed to int g_run_rc.  If any error is detected
during bdevperf running, negative return code is directly set to
g_run_rc. Then g_run_rc is passed to rpc_perform_tests_cb() or
bdevperf_fini().

Besides, we had updated g_run_failed even after spdk_app_start()
returned.  However return code of spdk_app_start() might not be of
bdevperf_run().  Hence change main() to return the return code of
spdk_app_start() simply without updating g_run_failed.

Additionally, even if g_target_count becomes zero in
spdk_bdevperf_shutdown_cb(), g_run_rc may indicate error.  So,
change spdk_bdevperf_shutdown_cb() to pass g_run_rc to
bdevperf_fini().
