Ira Weiny 15617dffa3 percpu_ref: Fix comment regarding percpu_ref_init flags ...

The comment for percpu_ref_init() implies that using
PERCPU_REF_ALLOW_REINIT will cause the refcount to start at 0.  But
this is not true.  PERCPU_REF_ALLOW_REINIT starts the count at 1 as
if the flags were zero.  Add this fact to the kernel doc comment.
