This change updates the 3ware drivers (3w-xxxx, 3w-9xxx, 3w-sas) email
addresses from linuxraid@lsi.com to aradford@gmail.com, since the old
email address doesn't exist.

This patch was updated to remove www.lsi.com text.

The 3w-sas driver needs to tear down the dma mappings before returning
the command to the midlayer, as there is no guarantee the sglist and
count are valid after that point.  Also remove the dma mapping helpers
which have another inherent race due to the request_id index.
