btrfs: get rid of btrfs_read_dev_super()
The function is introduced by commit a512bbf855ff ("Btrfs: superblock
duplication") at the beginning of btrfs.
It leaved a comment saying we'd need a special mount option to read all
super blocks, but it's never been implemented and there was not
need/request for it. The check/rescue tools are able to start from a
specific copy and use it as primary eventually.
This means btrfs_read_dev_super() is always reading the first super
block, making all the code finding the latest super block unnecessary.
Just remove that function and replace all call sites with
btrfs_read_disk_super(bdev, 0, false).
