dmu_tx kstat cleanup

A few counters in the dmu_tx kstats are obsolete or no longer
bumped properly.

- The sync task restructuring commit
  13fe019870c8779bf2f5b3ff731b512cf89133ef removed the code
  that bumpted dmu_tx_quota. The counter is now bumped in two
  cases, instead of just the one case as before (after the result
  of dsl_dataset_check_quota call). The second case is where
  we check the requested reservation against the actual pool size,
  as this is an implicit quota of sorts.

- The write throttle restructuring commit
  e8b96c6007bf97cdf34869c1ffbd0ce753873a3d makes dmu_tx_how and
  dmu_tx_inflight obsolete, so they are removed.
