Mateusz Guzik f750847daa mm: introduce get_task_exe_file ...

commit cd81a9170e69e018bbaba547c1fd85a585f5697a upstream.

For more convenient access if one has a pointer to the task.

As a minor nit take advantage of the fact that only task lock + rcu are
needed to safely grab ->exe_file. This saves mm refcount dance.

Use the helper in proc_exe_link.
