btrfs-progs: super-recover: fix double free fs_devices memory
super-recover collects btrfs devices infomation using existed
functions scan_one_devices().
Problem is fs_devices is freed twice in close_ctree() and
free_recover_superblock() for super correction path.
Fix this problem by checking whether fs_devices memory
have been freed before we free it.
