Bluetooth: host: Refresh advertiser NRPA when active scan is using NRPA

Browse source 
When starting a non-connectable advertiser and an active scanner is also
using NRPA address then this use-case should be supported. A new
advertiser that is non-connectable should have a fresh NRPA address
every time it is started, so we must refresh the NRPA used by the active
scanner.
