Use struct option_iter to walk over the individual options in the driver's option string. Replaces the hand-written strsep() loop with a clean interface. The helpers for struct option_iter handle empty option strings and empty options transparently. The struct's _init and _release functions duplicate and release the option string's memory buffer as needed. Done in preparation of constifying the option string.
