staging: line6: drop CONFIG_LINE6_USB_DUMP_PCM
The CONFIG_LINE6_USB_DUMP_PCM config option prints a hexdump of PCM
audio data as URBs are sent and received. The usbmon feature should be
used instead of manually dumping PCM URBs. There are a few advantages
to using usbmon:
* Can be turned on/off at runtime
* Provides full USB-level traffic
* tcpdump and wireshark support for powerful analysis
* No driver-specific code is required
This is the last user of line6_write_hexdump() so we drop it too.
