[PATCH 1/1] sched/deadline: Fix regression in cpudl_find.

[Reiter Wolfgang]

When using CONFIG_FTRACE_SELFTEST=y and CONFIG_FTRACE_STARTUP_TEST=y
best_cpu is -1 and passed to function cpumask_check which takes
unsigned int.
Fix order of test arguments to avoid oops.
Regression was introduced in commit 82b95800b256205cff2eeab5bbd03430d2d0f20d.
