[PATCH] mm-modem-helpers-qmi: avoid SIGSEGV with mmcli --set-current-bands

[Nick]

Hey,

Thanks Reinhard, it seems to be working now, but I have a new question.  I set the bands in mmcli then power cycled, testing on EM7565.  It seems like qmicli it is off by one, is that right?  Shouldn’t Qmicli report 3 and 28?  There is no band 29 in Australia, where I am.
