nv50/ir: allow load propagation when flags are defined
The old condition disallowed load propagation any time flags were
defined, even with e.g. set and a constbuf reference. The new condition
disallows it only with immediate propagation. (There are no opcodes that
set the condition flag and have an immediate argument.)
