cxgb4: fix TSO descriptors

Commit 1704d74894912b8ecc3e95cecd7bde336a0b1bf2 ("cxgb4vf: small changes
to message processing structures/macros") was incomplete and causes cxgb4
to write bad TSO descriptors.  Fix that up by reverting the offending part
of that commit and adjusting field accesses now that they are one level
deeper.
