Jiri Olsa 987999769e fs/proc/kcore.c: Clear ret value in read_kcore_iter after successful iov_iter_zero ...

commit 088f294609 upstream.

If iov_iter_zero succeeds after failed copy_from_kernel_nofault,
we need to reset the ret value to zero otherwise it will be returned
as final return value of read_kcore_iter.

This fixes objdump -d dump over /proc/kcore for me.
