[PATCH] kexec, remove panic_on_warn kernel parameter from kdump situations

[Prarit Bhargava]

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.
