staging: wilc1000: check if device is initialzied before changing vif

Browse Source 
[ Upstream commit 6df6f3849bb8f317bf2d52711aacea4292237ede ]

When killing hostapd, the interface is closed which deinitializes the
device, then change virtual interface is called.
This change checks if the device is initialized before sending the
interface change command to the device
