Li Zefan ed146b2594 ftrace: Fix unmatched locking in ftrace_regex_write() ...

When a command is passed to the set_ftrace_filter, then
the ftrace_regex_lock is still held going back to user space.

 # echo 'do_open : foo' > set_ftrace_filter
 (still holding ftrace_regex_lock when returning to user space!)
