Konstantin Belousov 2f7c18600c 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.
