msm: msm_bus: Fix scaling of ocmem core clock
msm: msm_bus: Fix scaling of ocmem core clock

An optimization in bus driver prevents checking of slave clocks if
the clock of the NoC on which the slave is connected is not
touched.
Since ocmem slave is represented on a virtual NoC, the ocmem core
clock was not being scaled. Fix this by checking for status of
slave clocks.
