wncss-start: ensure that 'state' field exists
with newer implementation of remoteproc, the 'state' field has been moved from
debugfs into /sys/class/remoteproc/xxx. So with newer kernel, wcnss-start will
find the WCN core, but starting the core would fail since 'state' does not exist
in debugfs. So let's add an additional check to make sure that this field exist
before using it.
