kdumpctl: Print warning in case the raw device is formatted and contains filesystem.

Browse Source 
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 kdumpctl prints
a warning in case it finds the raw device to be formatted.
