Subject: [PATCH] locks: kill redundant local variable

From: \"J. Bruce Fields\" <bfields@...ldses.org>

There's no need for another variable local to this loop; we can use the
variable (of the same name!) already declared at the top of the function,
and not used till later (at which point it's initialized, so this is safe).
