[PATCH] opcodes/nfp: skip those non-code sections

[Yinjun Zhang]

AddressSanitizer detects heap-buffer-overflow when running
"objdump -D" for nfp .nffw files.

Currently nfp disassemblers can only support code section, and
we don't require to disassmeble other sections for now. So skip
the non-code sections.
