Fix double free of memory if btrfs_open_devices fails: *** Error in `btrfs': double free or corruption (fasttop): 0x000000000066e020 *** Crash happened because when open failed on device inside btrfs_open_devices it freed all memory by calling btrfs_close_devices but inside disk-io.c we call btrfs_close_again it again.
