HID: lg4ff: validate report length before fixed offsets

lg4ff_raw_event() rewrites fixed report offsets when combined pedals are
enabled. It currently assumes that each product report contains every
source and destination byte used by the rewrite.

Return without rewriting a short report before each product-specific
access. Apply the same bound to the computed offset path.
