Subject: [PATCH v7 16/30] soc: fsl: cpm1: qmc: Check available timeslots in qmc_check_chans()

The timeslots checked in qmc_check_chans() are the timeslots used.
With the introduction of the available timeslots, the used timeslots
are a subset of the available timeslots. The timeslots checked during
the qmc_check_chans() call should be the available ones.

Simply update and check the available timeslots instead of the used
timeslots in qmc_check_chans().
