The header comment for both start_poll_synchronize_rcu() and
start_poll_synchronize_rcu_full() state that interrupts must be enabled
when calling these two functions, and there is a lockdep assertion in
start_poll_synchronize_rcu_common() enforcing this restriction. However,
there is no need for this restrictions, as can be seen in call_rcu(),
which does wakeups when interrupts are disabled.
This commit therefore removes the lockdep assertion and the comments.
