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.
