kernel-doc: strip leading whitespace from continued param descs
If a param description spans multiple lines, check any leading whitespace in the first continuation line, and remove same amount of whitespace from following lines. This allows indentation in the multi-line parameter descriptions for aesthetical reasons while not causing accidentally significant indentation in the rst output.
