Subject: [PATCH] bpf: bpftool: convert ‘const char *’ type into 'char *' in assignment

When compiling with check flag: make -C tools/bpf/bpftool/
gcc will warning:

jit_disasm.c:119:29: warning: assignment discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
   info.disassembler_options = disassembler_options;

So convert 'const char *' type into 'char *' to fix the warning.

Fixes:3ddeac6705aba(tools: bpftool: use 4 context mode for the NFP disasm)
