[PATCH 2/2] btrfs: maintain consistent fmode flags for device open

[Anand Jain <anand.jain@oracle.com>]

Devices opened through replace/add would have FMODE_WRITE | FMODE_EXCL,
as compared with devices opened through the mount which will have
FMODE_READ | FMODE_WRITE | FMODE_EXCL. So maintain consistency.
