[PATCH] kdump.sysconfig.s390: Remove "prot_virt" from kdump kernel cmdline
"prot_virt" enables host protected virtual machines on s390. This
requires a minimum of ~2.5GB memory and thus exceeds what is typically
reserved for the crashkernel. Thus remove "prot_virt" from the command
line for the 2nd kernel to prevent it to run out-of-memory.
