[PATCH] staging: wilc1000: assign scan result callback before starting the scan

[<Adham.Abozaeid@microchip.com>]

From: Adham Abozaeid <adham.abozaeid@microchip.com>

When scan is triggered, sometimes scan results are received before the scan
result callback is assigned, causing the recieved results to be ignored.
