net: ipa: move version test inside ipa_endpoint_program_delay()
IPA version 4.2 has a hardware quirk that affects endpoint delay
mode, so it isn't used there. Isolate the test that avoids using
delay mode for that version inside ipa_endpoint_program_delay(),
rather than making that check in the caller.
