HID: i2c-hid: fix handling numbered reports with IDs of 15 and above

Special handling of numbered reports with IDs of 15 and above is only
needed when executing what HID-I2C spec is calling "Class Specific
Requests", and not when simply sending output reports.

Additionally, our mangling of report ID in i2c_hid_set_or_send_report()
resulted in incorrect report ID being written into SET_REPORT command
payload.

To solve it let's move all the report ID manipulation into
__i2c_hid_command() where we form the command data structure.
