ftrace: Add ftrace_set_filter_ips function
Adding ftrace_set_filter_ips function to be able to set filter on
multiple ip addresses at once.
With the kprobe multi attach interface we have cases where we need to
initialize ftrace_ops object with thousands of functions, so having
single function diving into ftrace_hash_move_and_update_ops with
ftrace_lock is faster.
The functions ips are passed as unsigned long array with count.
