Waiman Long cb037fdad6 locking/qspinlock: Use smp_cond_acquire() in pending code ...

The newly introduced smp_cond_acquire() was used to replace the
slowpath lock acquisition loop. Similarly, the new function can also
be applied to the pending bit locking loop. This patch uses the new
function in that loop.
