wifi: wilc1000: add missing unregister_netdev() in wilc_netdev_ifc_init()
Fault injection test reports this issue:
kernel BUG at net/core/dev.c:10731!
invalid opcode: 0000 [#1] PREEMPT SMP KASAN PTI

The root case here is alloc_ordered_workqueue() fails, but
cfg80211_unregister_netdevice() or unregister_netdev() not be called in
error handling path. To fix add unregister_netdev goto lable to add the
unregister operation in error handling path.
