[PATCH tip/core/rcu 65/88] rcu: move rcutiny.h to the new true/false-function style

[Paul E. McKenney]

This commit saves a few lines in include/linux/rcutiny.h by moving to
single-line definitions for functions that just return either true or
false, instead of the old style where the two curly braces each get
their own line.  This commit also applies the same transformation to
rcu_all_qs(), which contains just barrier().
