[PATCH] locking/qspinlock: Clarify pending field layout

[WEI-HONG, YE]

For CONFIG_NR_CPUS < 16K, _Q_PENDING_BITS is 8 and the pending
field occupies bits 8-15 of the lock word. The current comment
documents bit 8 as pending and bits 9-15 as unused, which describes
the pending flag value rather than the field layout.

Describe bits 8-15 as the pending byte so the layout description
is consistent with the lock byte.
