Single-kernel grubby updates the BLS entry but not /etc/kernel/cmdline, so every later kernel install sees a stale crashkernel value and repeats the reset warning. Fixes: RHEL-188906

Summary
After a single-kernel
grubby --update-kernelcrashkernel change, alsoupdate
/etc/kernel/cmdline. That stops the reset warning from firingon every kernel update.
Does not use
--update-kernel=ALL, so other kernels keep their owncrashkernel values.

Test plan
dnf reinstall kernel-core: cmdline matches the default after first reset
