Bugfix: 1) incorrect FMLP high prio task tracking and 2) race in print statement

1) High priority task tied to FMLP semaphore in P-EDF scheduling is
   incorrectly tracked for tasks acquiring the lock without
   contention.  (HP is always set to CPU 0 instead of proper CPU.)
2) Race in a print statement from P-EDF's pi_block() causes NULL
   pointer dereference.
