ftrace: Move ftrace_filter_lseek out of CONFIG_DYNAMIC_FTRACE section
commit 7f49ef69db6bbf756c0abca7e9b65b32e999eec8 upstream.
As ftrace_filter_lseek is now used with ftrace_pid_fops, it needs to
be moved out of the #ifdef CONFIG_DYNAMIC_FTRACE section as the
ftrace_pid_fops is defined when DYNAMIC_FTRACE is not.
