panic_on_warn kernel parameter will cause the kernel to panic when a
WARN() is hit in the kernel. This is not a good situation for the kdump
kernel because then it would be possible for the kdump kernel to panic in
a non-fatal WARN().
This patch removes panic_on_warn as a kernel parameter for the kdump
kernel.
