[PATCH 2 04/24] hpsa: allow passthru ioctls to work with bidirectional commands

["Stephen M. Cameron" <scameron@beardog.cce.hp.com>]

From: Stephen M. Cameron <scameron@beardog.cce.hp.com>

Treat the the data direction bits as a bit mask allowing both
READ and WRITE at the same time instead of testing for equality
to see if it's a exclusively a READ or a WRITE.
