For riscv host, it will set dec->cfg to zero. Thus we shuld guard
the dec->cfg deference for riscv host disassemble.
And in general, we should only use dec->cfg for target in three cases:
1) For not incompatible encodings, such as zcmp/zcmt/zfinx.
2) For maybe-ops encodings, they are better to be disassembled to
the "real" extensions, such as zicfiss. The guard of dec->zimop
and dec->zcmop is for comment and avoid check for every extension
that encoded in maybe-ops area.
3) For custom encodings, we have to use dec->cfg to disassemble
custom encodings using the same encoding area.
