btrfs: remove unused btrfs_root::type

Looks like the struct member was added in 2007 in 2.6.29 in commit
87ee04eb0f2f ("Btrfs: Add simple stripe size parameter") but hasn't been
used at all since. So let's remove it. This was found by tool
https://github.com/jirislaby/clang-struct, then build tested after
removing the struct member.
