btrfs: remove unused member btrfs_root::name 



Added in 58176a96 ("Btrfs: Add per-root block accounting and sysfs
entries") in 2007, the roots had names exported in sysfs. The code
was commented out in 4df27c4d ("Btrfs: change how subvolumes
are organized") and cleaned by 182608c8 ("btrfs: remove old
unused commented out code").
