[PATCH v2] HID: i2c-hid: use print_hex_dump_debug to print report descriptor

[Riwen Lu]

From: Riwen Lu <luriwen@xxxxxxxxxx>

The format '%*ph' print up to 64 bytes long as a hex string with ' '
sepatator. Usually the size of report descriptor is larger than 64
bytes, so consider using print_hex_dump_debug to print out all of it for
better debugging.

Signed-off-by: Riwen Lu <luriwen@xxxxxxxxxx>

v1->v2:
 - Add a prefix for the hex dump.
