Christian Brauner 25ab7b6f34 xattr: remove rbtree-based simple_xattr infrastructure ...

Now that all consumers (shmem, kernfs, pidfs) have been converted to
use the rhashtable-based simple_xattrs with pointer-based lazy
allocation, remove the legacy rbtree code path. The rhashtable
implementation provides O(1) average-case lookup with RCU-based lockless
reads, replacing the O(log n) rbtree with reader-writer spinlock
contention.
