According to HUTRR39 logical sensor devices may be nested inside
physical collections or may be specified in multiple top-level
application collections (see page 59, strategies 1 and 2). However,
the current code was only recognizing those with physical collections.
This issue turned up in recent MacBook Pro's which define the ALS in
a top-level application collection.

Better not use language extensions. Simple to use
report->field[i]->physical ? report->field[i]->physical : report-

Otherwise patch is fine.

Since there are some hid core change, Jiri needs to check. If Jiri is
fine with hid core changes:
