platform-mc: Fix missing returns from sensor creation

Currently when an error occurs during numeric sensor addition, the code
calls addNextSensorFromPDRs() to schedule the next item but doesn't
return from the function.
This may lead to undesired behavior: the function invokes
addNextSensorFromPDRs() for the second time, incrementing the iterator
again, so some sensors may be skipped.
Add the missing returns to terminate execution after advancing the
iterator.
