Fix to make the translation of extern object & function mailbox fields
(e.ext_obj.field and f.ext_func.field) work for the add/sub, shl/shr,
jmplt/jmpgt instructions.

Fixes: baf7999303d0 ("pipeline: introduce SWX add instruction")
Fixes: c88c62943818 ("pipeline: introduce SWX subtract instruction")
Fixes: b09ba6d0a3c2 ("pipeline: introduce SWX SHL instruction")
Fixes: e0f51638b715 ("pipeline: introduce SWX SHR instruction")
Fixes: b3947e25bed4 ("pipeline: introduce SWX jump and return instructions")
Cc: stable@dpdk.org

I think it deserves it bit more explanations.

Thanks, Thomas, this is a relatively low level issue, so I found it difficult to explain in just a few words, but I will give it another shot in v2 that I am going to send now.
