[PATCH] testsuite/smokey: rtdm: Give delayed close more time for running in QEMU

[Jan Kiszka]

From: Jan Kiszka <jan.kiszka@siemens.com>

RTTST_RTIOC_RTDM_DEFER_CLOSE causes a 300 ms delay by the driver. We
only added 1 ms plus the open/close of the second device, and that was
sometimes too short when running in QEMU:

2021-06-18T18:58:41 FAILED run_rtdm:186: open returned -16 instead of 12 - Device or resource busy

Make it 100 ms in that case, to be safe.
