mkfs created more than one fs_devices in fs_uuids.
1: one is for file system been created
2: others are created in test_dev_for_mkfs for check mount point
   test_dev_for_mkfs()-> ... -> btrfs_scan_one_device()

Current code only close above 1, and this patch close above 2.

Similar problem exist in other tools, for ex:
 cmd-check.c: the function is:
 cmd_check()->check_mounted()-> ... -> btrfs_scan_one_device()
 ...
