Anand Jain aa64f6f0ce btrfs: use the correct superblock to compare fsid in btrfs_validate_super 
commit d167aa76dc upstream.

The function btrfs_validate_super() should verify the fsid in the provided
superblock argument. Because, all its callers expect it to do that.

Such as in the following stack:

   write_all_supers()
       sb = fs_info->super_for_commit;
       btrfs_validate_write_super(.., sb)
         btrfs_validate_super(.., sb, ..)

   scrub_one_super()
	btrfs_validate_super(.., sb, ..)

And
   check_dev_super()
	btrfs_validate_super(.., sb, ..)

However, it currently verifies the fs_info::super_copy::fsid instead,
which is not correct.  Fix this using the correct fsid in the superblock
argument.
