Hello, 
These changes fix the following compiler warnings of the function
unregister_ftrace_direct.

The warnings happen using GCC compiler, enabling the ftrace related 
configs and using the command 'make W=1'.

kernel/trace/ftrace.c:5489: warning: Function parameter or struct member
'addr' not described in 'unregister_ftrace_direct'

kernel/trace/ftrace.c:5489: warning: Function parameter or struct member 
'free_filters' not described in 'unregister_ftrace_direct'
