From: Kenneth D'souza <kdsouza@redhat.com>

Currently the kdumpctl script doesn't check if the raw device is
formatted which might destroy existing data at the time of dump
capture.

This patch addresses this issue, by ensuring that the kdumpctl
errors out in case it finds the raw device to be formatted.
