HID: hyperv: Correctly access fields declared as __le16
Add the use of le16_to_cpu() for fields declared as __le16. Because
Hyper-V only runs in Little Endian mode, there's no actual bug.
The change is made in the interest of general correctness in
addition to making sparse happy. No functional change.
