cxgbe(4): Fixes to tx coalescing.

- The behavior implemented in r362905 resulted in delayed transmission
  of packets in some cases, causing performance issues.  Use a different
  heuristic to predict tx requests.

- Add a tunable/sysctl (hw.cxgbe.tx_coalesce) to disable tx coalescing
  entirely.  It can be changed at any time.  There is no change in
  default behavior.

(cherry picked from commit 3447df8bc5b342bd88d565641435284ff620ee2a)
