Zqiang 51f5f78a4f srcu: Make Tiny synchronize_srcu() check for readers 
This commit adds lockdep checks for illegal use of synchronize_srcu()
within same-type SRCU read-side critical sections and within normal
RCU read-side critical sections.  It also makes synchronize_srcu()
be a no-op during early boot.

These changes bring Tiny synchronize_srcu() into line with both Tree
synchronize_srcu() and Tiny synchronize_rcu().
