docs: virsh: Added note for the dump command

Crash dump in a old kvmdump format is being obsolete and cannot be loaded and
processed by crash utility since its version 6.1.0. A --memory-only option is
required in order to produce valid ELF file which can be later processed by the
crash utility. A new note is added to the dump command description.
