megasas: Replace trace_megasas_dcmd_dump_frame()

trace_megasas_dcmd_dump_frame() takes 9 arguments, which is
rather much. Plus the trace infrastructure doesn't support
it.  As we can get the information via other means it's pointless
to have it in the driver, so rather use some proper trace
point here and remove the old one.
