i965/blorp/gen6: Use normal base state address setup

This is identical to the blorp version which only differs in case
fragment shader isn't used. In that case blorp would reset batch
buffer address to zero.
This is not really needed, and having blorp to use base state
address setup that is compatible with normal upload allows one to
skip resetting it.
