Colin Ian King 41a0c249cb proc: fix -ESRCH error when writing to /proc/$pid/coredump_filter 
Writing to /proc/$pid/coredump_filter always returns -ESRCH because commit
774636e19e ("proc: convert to kstrto*()/kstrto*_from_user()") removed
the setting of ret after the get_proc_task call and incorrectly left it as
-ESRCH.  Instead, return 0 when successful.

Example breakage:

  echo 0 > /proc/self/coredump_filter
  bash: echo: write error: No such process

Fixes: 774636e19e ("proc: convert to kstrto*()/kstrto*_from_user()")
