PAL: Handle deferred switch on every start

Consider SVA without lab case, if LPI<->NLPI switch is deferred when
second stage is getting processed, as stream will be in buffering state,
but after second stage detection, deferred switch is not getting handled.

Now, while doing every start, it will check if switch was deferred or not,
and handle it accordingly, as after every detection/rejection/lab data, stream
will get either unload or start event, and in case of unload we don't need to
do anything, for start we will handle it.
