Fix debug prints when loading to flash

Browse Source 
While loading to flash with debug level at least 3,
OpenOCD tries to print the whole loaded bitstream.
This will be very-very-slow due to implementation of
conversion from buffer to string.

* fix condition on selected debug level in jtag/core.c
* replace slow buf_to_str function from helper/binarybuffer.c
  with faster but_to_hex_str function
