[PATCH] md: make recovery started by do_md_run() visible via sync_action

[Dan Williams <dan.j.williams@intel.com>]

By default md_do_sync() will perform recovery if no other actions are
specified.  However, action_show() relies on MD_RECOVERY_RECOVER to be
set otherwise it returns 'idle'.  So, add a missing set
MD_RECOVERY_RECOVER when starting recovery.

Hi Neil,

One more to finish off recovery checkpoint support.  Without this mdmon
never notices that the array was rebuilding and never marks the
completion.  I did not see any urgency to workaround this in the mdadm
patchset, but let me know if you think a "kernel version > 2.6.33-rcX"
check is warranted.

Thanks,
Dan
