lib/generic-radix-tree.c: remove unneeded __rcu

Browse Source 
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.
