usb: gadget: f_hid: fix endianness issue with descriptors

Running sparse checker it shows warning message about
incorrect endianness used for descriptor initialization:

| f_hid.c:91:43: warning: incorrect type in initializer (different base types)
| f_hid.c:91:43:    expected restricted __le16 [usertype] bcdHID
| f_hid.c:91:43:    got int

Fixing issue with cpu_to_le16() macro, however this is not a real issue
as the value is the same both endians.
