staging: dgrp: prefix function names with dgrp_ in dgrp_specproc.c

Browse Source 
Prefix the functions in dgrp_specproc.c to avoid ambiguity in backtraces, such
as the "info_proc_open" in this one:

unreferenced object 0xffff88003b6696e0 (size 32):
  comm "cat", pid 2321, jiffies 4294705179 (age 29.434s)
