[PATCH 2/4] imsm: FIX: spare cannot be added

[Adam Kwolek <adam.kwolek@intel.com>]

When Manage.c adds spare, it calls write_init_super() and this function
is responsible for closing disk handle (Manage.c:812).
For imsm case this handle is reused for managing this disk and handle
(due to this it is not closed).
As handle was opened with flag O_EXCL, adding disk to md fails on writing
to new_dev (md cannot set lock on device).
To resolve situation close current handle and open new one without O_EXCL flag.
