HID: only dump report traffic with debug level 2 

Currently using debug=1 with hid module prints out all sent and received
reports to the kernel log, while in many cases we only want to see the
report descriptors and hid-input mappings that are printed when a device
is probed.

Add new level debug=2, and only dump the report traffic with that level.
