broadband-modem-qmi: split up peek_port_qmi_for_data()

peek_port_qmi_for_data() is currently quite confusing to read because it
mostly covers qmi_wwan while the mhi_net case returns early. Split this
up into separate functions per driver to make it less confusing, similar
to the variant in mm-broadband-modem-qmi-qcom-soc.

No functional change.
