Thread: Fix a comment in WalSnd structure

Hi,

WalSnd structure mutex is being used to protect all the variables of
that structure, not just 'variables shown above' [1]. A tiny patch
attached to fix the comment.

Thoughts?

Yep, walsender.c tells the same story, aka that replyTime and latch
are updated with the spinlock taken.  I'll go update the comment, and
you suggestion sounds fine to me.
