Revert "nir/lower_indirect: Bail early if modes == 0"

Browse source 
"There's no point in walking the program if we're never going to
    actually lower anything."

Except we might lower compacted local arrays.  In that case, modes will
be 0, but there is still lowering to be done.

This reverts commit 7f75cf2a94.
