btrfs: Remove unused variables
clear_super - usage was removed in commit cea67ab92d3d ("btrfs: clean
the old superblocks before freeing the device") but that change forgot
to remove the actual variable.
max_key - commit 6174d3cb43aa ("Btrfs: remove unused max_key arg from
btrfs_search_forward") removed the max_key parameter but it forgot to
remove references from callers.
stripe_len - this one was added by e06cd3dd7cea ("Btrfs: add validadtion
checks for chunk loading") but even then it wasn't used.
