[kernel,v1,1/1] Bluetooth: hci_sync: Fix resuming passive scan after suspend resume

Commit Message

After resuming, remove setting scanning_paused to false, because it is
checked and set to false in hci_resume_scan_sync. Also move setting
the value to false before updating passive scan, because the value is
used when resuming passive scan.

unfiltered passive scan)
