md: Fix rdev_size_store with size == 0
Fix rdev_size_store with size == 0. size == 0 means to use the largest size allowed by the underlying device and is used when modifying an active array. This fixes a regression introduced by commit d7027458d68b2f1752a28016dcf2ffd0a7e8f567 Cc: <stable@kernel.org> Signed-off-by: Chris Webb <chris@arachsys.com> Signed-off-by: NeilBrown <neilb@suse.de>
