iris: Re-emit Surface State Base Address when context is lost.

When we hit a GPU hang, we failed to reset Surface State Base Address
right away, and would keep hanging until we filled up the binder.  Then
we'd finally get it right after a lot of repeated stumbles.  Update it
right away so we hopefully hang fewer times before succeeding.
