coredump: cleanup "ispipe" code
- kill "int dump_count", argv_split(argcp) accepts argcp == NULL.
- move "int dump_count" under " if (ispipe)" branch, fail_dropcount
can check ispipe.
- move "char **helper_argv" as well, change the code to do argv_free()
right after call_usermodehelper_fns().
- If call_usermodehelper_fns() fails goto close_fail label instead
of closing the file by hand.
