Fix documentation of panic_on_warn

Browse Source 
The kernel cmdline option panic_on_warn expects an integer, it is not a
plain option as documented. A number of uses in the tree figured this
already, and use panic_on_warn=1 for their purpose.

Adjust a comment which otherwise may mislead people in the future.
