HID: wacom: generic: read HID_DG_CONTACTMAX from any feature report
commit 184eccd40389df29abefab88092c4ff33191fd0c upstream.
In the generic code path, HID_DG_CONTACTMAX was previously
only read from the second byte of report 0x23.
Another report (0x82) has the HID_DG_CONTACTMAX in the
higher nibble of the third byte. We should support reading the
value of HID_DG_CONTACTMAX no matter what report we are reading
or which position that value is in.
To do this we submit the feature report as a event report
using hid_report_raw_event(). Our modified finger event path
records the value of HID_DG_CONTACTMAX when it sees that usage.
