tsleep_interlock - Fix bug with TDF_TSLEEPQ

* LWKT previously disallowed the scheduling of a thread flagged
  TDF_TSLEEPQ because the tsleep queue was the same as the threadq.
  Now that they are different, it is possible for the thread to
  still be on a tsleepq when descheduled and later rescheduled.
  Remove the check, allowing the thread to be rescheduled by LWKT.

  This fixes issues with processes just locking up in "D"isk wait.
