kcmp: In get_file_raw_ptr use task_lookup_fd_rcu

Modify get_file_raw_ptr to use task_lookup_fd_rcu. The helper
task_lookup_fd_rcu does the work of taking the task lock and verifying
that task->files != NULL and then calls files_lookup_fd_rcu. So let
use the helper to make a simpler implementation of get_file_raw_ptr.
