broadband-modem-qmi: Introduce udev flag for reduced facility lock query

Browse Source 
The udev flag "ID_MM_QMI_FACILITY_LOCK_QUERY_REDUCED" allows to skip
facility lock state query "get_ck_status" on the DMS path for devices
where this isn't implemented properly.

On devices that have enabled "device locks", this flag won't work well.
Skipping the query doesn't disable the locks.

Fixes #448
