btrfs: add missing RCU unlock in error path in try_release_subpage_extent_buffer()
commit b2840e33127ce0eea880504b7f133e780f567a9b upstream.
Call rcu_read_lock() before exiting the loop in
try_release_subpage_extent_buffer() because there is a rcu_read_unlock()
call past the loop.
This has been detected by the Clang thread-safety analyzer.
