[PATCH 3/3] exec: proc_exec_connector() should be called only once

[Oleg Nesterov <oleg@redhat.com>]

A separate one-liner with the minor fix.

PROC_EVENT_EXEC reports the "exec" event, but this message
is sent at least twice if search_binary_handler() is called
by ->load_binary() recursively, say, load_script().

Move it to exec_binprm(), this is "depth == 0" code too.
