[PATCH] osmo-ttcn3-hacks[master]: L1CTL: Try FBSB up to 10 times in f_L1CTL_FBSB()

[Harald Welte]

Review at  https://gerrit.osmocom.org/7232

L1CTL: Try FBSB up to 10 times in f_L1CTL_FBSB()

For some reason, even with a perfectly valid/strong signal, the FBSB
task sometimes fails in the firmware.  Let's wrap a loop around
it and try up to 10 times before failing the test.
