broadband-modem-mbim: fix preservation logic for PIN1 unlock retries

Browse Source 
This patches fixes commit 334273979 "broadband-modem-mbim: preserve
unlock retries for PIN1 when appropriate", which doesn't correctly
propagate the unlock retries information for PIN1 observed from
responses to MBIM_CID_PIN set operations (see commit eb9ec1b61
"sim-mbim: update unlock retries information after PIN operations").
