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.
