lib/generic-radix-tree.c: remove unneeded __rcu
struct __genradix is defined as having its member 'root' annotated as __rcu. But in the corresponding API RCU is not used. Sparse reports this type mismatch as: lib/generic-radix-tree.c:56:35: warning: incorrect type in initializer (different address spaces) lib/generic-radix-tree.c:56:35: expected struct genradix_root *r lib/generic-radix-tree.c:56:35: got struct genradix_root [noderef] <asn:4> *__val with 6 other ones. So, correct root's type by removing this unneeded __rcu.
