[DAG] Early exit for flags in canCreateUndefOrPoison [nfc] (#89834)

This matches the style used in the Analysis version of this routine, and
makes it less likely we'll miss a poison generating flag in future
changes. Unlike IR, the check for poison generating flags doesn't need
to switch over opcode since all nodes have the SDFlags storage.
