[MiSched] Fix a logic error in tryPressure()
Fixes a logic error in the MachineScheduler found by Steve Montgomery

fix has been found to introduce some small performance regressions.
However, Andy has recommended that, at this point, we fix this to
avoid further dependence on the incorrect behavior (and then

Kernel threads (and processes) are supposed to call kthread_exit() (or

fork_exit() to force a kthread exit if a kernel thread's "main" routine

and was not updated to call kthread_exit() instead of kproc_exit() when
threads were added to the kernel.
This mistake was particularly exciting when the errant thread belonged to
proc0. Due to the missing P_KTHREAD flag the fallback did not kick in
and instead tried to return to userland via whatever garbage was in the
trapframe. With P_KTHREAD set it tried to terminate proc0 resulting in
other amusements.
