Change l2arc_norw default to zero

These days modern SSDs can efficiently service concurrent reads
and writes.  When this flag was added that wasn't really the
case for a variety of SSD controllers.  But now we can set the
default value to take advantage of this parallelism and only
disable this as needed for specific troublesome hardware.
