[PATCH RFC v2 14/24] hazptrtorture: Pass hazptr_pending to hazptr_torture_reader_tail()

[Paul E. McKenney]

This commit passes a hazptr_pending structure instead of a pair of
pointers to the hazptr_torture_reader_tail() function in order to make it
easier to test the releasing of hazard pointers from interrupt handlers.
