md: don't abort checking spares as soon as one cannot be added.

As spares can be added manually before a reshape starts, we need to
find them all to mark some of them as in_sync.

Previously we would abort looking for spares when we found an
unallocated spare what could not be added to the array (implying there
was no room for new spares).  However already-added spares could be
later in the list, so we need to keep searching.
