kdumpctl: Simplify fadump handling in reset_crashkernel
When handling fadump there are three cases we need to consider
1) When running on non-ppc64le systems
In this case _dump_mode=kdump and _new_fadump='' always. In other
words we don't need to care updating the fadump parameter on the
kernel command line. We could always remove it like the code did so
far. But should we remove it when we never set it? In particular as
that might overwrite a change explicitly made by the user (for
whatever reason)
2) When running on ppc64le and the user provided --fadump option
In this case _new_fadump and _dump_mode are set accordingly to what
the user provided. Thus we need to update both the crashkernel (in
case fadump was turned on/off) and the fadump (in case the fadump
mode changed) parameters.
3) When running on ppc64le but the user did not provide --fadump option
In this case both _new_fadump='' and _dump_mode=''. In this case we
take over the previously set fadump parameter. Which means that we
don't need to update the fadump parameter at all. We do need to check
whether the _new_dump_mode is fadump or kdump though so we use the
correct (new) default crashkernel value.
In the three cases only the second one needs to update the fadump
parameter. Reflect this discussion in code.
This also fixes a bug that always prints
kdump: Updated fadump= for kernel=$kernel. Please reboot the
system for the change to take effect.
when the crashkernel= parameter is unchanged as well as reboots the
system, if --reboot is provided. Even for non-ppc architectures.
