Allow "--write-behind=" to be done in grow mode.

From: Ian Dall <ian@beware.dropbear.id.au>

I have a small patch to mdadm which allows the write-behind amount to be
set a array grow time (instead of currently only at grow or create
time). I have tested this fairly extensively on some arrays built out of
loop back devices, and once on a real live array.
