bcachefs: Improve btree_path_relock_fail tracepoint

In https://github.com/koverstreet/bcachefs/issues/450, we're seeing
unexplained btree_path_relock_fail events - according to the information
currently in the tracepoint, it appears the relock should be succeeding.

This adds lock counts to the tracepoint to help track it down.
