USB: mos7840: fix big-endian probe

commit d551ec9b690f3de65b0091a2e767f1382adc792d upstream.

Fix bug in device-type detection on big-endian machines originally
introduced by commit 0eafe4de ("USB: serial: mos7840: add support for
MCS7810 devices") which always matched on little-endian product ids.
