HID: picoLCD: bounds check in dump_buff_as_hex()

Browse source

Make sure we keep enough space for terminating NUL character after last
newline. If we have too much data, replace last byte with '.'s to
make overflow visible.

Using hex_dump_to_buffer() is not interesting as it adds more overhead
and does not append the trailing linefeed.
