locking: Reduce the number of locks in ww_mutex stress tests
The stress test in test_ww_mutex_init() uses 4095 locks since
lockdep::reference has 12 bits, and since we are going to reduce it to
11 bits to support lock_sync(), and 2047 is still a reasonable number of
the max nesting level for locks, so adjust the test.
