ftrace: Assign ftrace_list_end to ftrace_ops_list type cast to RCU
Use a type cast to convert ftrace_list_end to RCU when assigning
ftrace_ops_list. This will quiet the sparse warning:
kernel/trace/ftrace.c:125:59: warning: incorrect type in initializer (different address spaces)
kernel/trace/ftrace.c:125:59: expected struct ftrace_ops [noderef] __rcu *[addressable] [toplevel] ftrace_ops_list
kernel/trace/ftrace.c:125:59: got struct ftrace_ops *
