cpu/rt: Fix cpu_hotplug variable initialization
The commit "cpu/rt: Rework cpu down for PREEMPT_RT" changed the double meaning of the cpu_hotplug.lock, where it was a spinlock for RT and a mutex for non-RT, to just a mutex for both. But the initialization of the variable was not updated to reflect this change. Cc: stable-rt@vger.kernel.org Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
