The r254167 moved initialization of the sleepqueues before the witness
is operational. init_sleepqueues() initializes 256 mutexes, which,
due to witness still being cold, started to overflow the pending_locks
array.
As stated in the reported panic message, increase WITNESS_PENDLIST
from 768 to 1024, which provides space for additional 256 locks.
