The purpose of the "busted" torture type is to test rcutorture code paths
used only when a too-short grace period is detected. Currently, "busted"
only uses normal rcu_read_lock()-style readers, which fails to exercise
much of the "Failure/close-call rcutorture reader segments" functionality.
This commit therefore sets the .extendables field of rcu_busted_ops to
RCUTORTURE_MAX_EXTEND in order to more fully exercise the reporting.
