isl/gen7: remove unneeded ISL_DEV_GEN check

The function gen7_format_needs_valign2 has two callers - the gen7 only
gen7_choose_valign_el() and isl_gen6_filter_tiling(). The latter of
which already guarding the invocation appropriately.

To be extra cautious add a couple of asserts alongside the removal of the
runtime check.
