Chris Mason 240f62c875 Btrfs: use RCU instead of a spinlock to protect the root node 
The pointer to the extent buffer for the root of each tree
is protected by a spinlock so that we can safely read the pointer
and take a reference on the extent buffer.

But now that the extent buffers are freed via RCU, we can safely
use rcu_read_lock instead.
