kdump-load: Add usage/help messages to this script

The kdump-load script is the only one that has more than a
single functionality, potentially being invoked in different ways.

With that in mind, just add a small usage/help for users'
information (thanks Emil for the suggestion).

While at it, changed the additional commands to be more friendly
and require exactly one command to be passed - changes summary:
s/initrd/create-initrd
s/clear/clear-initrd
s//load
