rcu: Move rcupdate.h to new empty-function style
This commit saves a few lines in include/linux/rcupdate.h by moving to single-line definitions for empty functions, instead of the old style where the two curly braces each get their own line. Reported-by: Ingo Molnar <mingo@kernel.org> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
