devlink: Fix binary values print

devlink: Fix binary values print

Fix function pr_out_binary_value() to start printing the binary buffer
from offset 0 instead of offset 1. Remove redundant new line at the
beginning of the output

Example:
With patch:
 mlx5e_txqsq:
   05 00 00 00 05 00 00 00 01 00 00 00 00 00 00 00
   00 00 00 00 00 00 00 00 8e 6e 3a 13 07 00 00 00
   00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
   c0
Without patch
  mlx5e_txqsq:

  00 00 00 05 00 00 00 01 00 00 00 00 00 00 00 00
  00 00 00 00 00 00 00 8e 6e 3a 13 07 00 00 00 00
  00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 c0
