lagg: Further cleanup of the rr_limit option.

Add an option flag so that arbitrary updates to a lagg's configuration
do not clear sc_stride.  Preseve compatibility for old ifconfig
binaries.  Update ifconfig to use the new flag and improve the casting
used when parsing the option parameter.

Modify the RR transmit function to avoid locklessly reading sc_stride
twice.  Ensure that sc_stride is always 1 or greater.
