[PATCH v18 12/17] kdump: Reduce unused parameters of parse_crashkernel_{high|low}

[Zhen Lei <thunder.leizhen@xxxxxxxxxx>]

The parameters 'system_ram' and 'crash_base' is only needed by the case of
"crashkernel=X@[offset]". The argument list of parse_crashkernel_suffix()
can help prove this point.
