nv50: mark scissors/viewports dirty on context switch

Commit 246ca4b001 ("nv50: implement multiple viewports/scissors, enable
ARB_viewport_array") added dirty tracking to scissors/viewports. However
it neglected to mark them all as dirty on a context switch. This fixes
an apparent regression in webgl in chrome, but probably in any
application that switches contexts.
