sched: Add "const" to is_idle_task() parameter
This patch fixes a build warning in -next due to a const pointer being passed to is_idle_task(). Because is_idle_task() does not modify anything, this commit adds the "const" to is_idle_task()'s argument declaration. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
