rcutorture: Drop sparse lock-acquisition annotations

Browse source 
The sparse __acquires() and __releases() annotations provide very
little value.  The argument is ignored, so sparse cannot tell the
differences between acquiring one lock and releasing another on the one
hand and acquiring and releasing a given lock on the other.  In addition,
lockdep annotations provide much more precision, for but one example,
actually knowing which lock is held.

This commit therefore removes the __acquires() and __releases()
annotations from rcutorture.
