uqmi: added timeout to fix hanging qmi.sh

Browse Source 
Modems which are using qmi do not reply on the 1st sync but they do
on subsequent. So qmi.sh is hanging on the first call. Since 2020 uqmi
supports a timeout parameter. Unfortunately qmi.sh didn't make use of
this parameter. So qmi.sh is now invoking an early dummy access to
unlock the modem
