invalid opcode: 0000 [#1] PREEMPT SMP KASAN PTI
Call Trace:
  <TASK>
  wilc_netdev_ifc_init+0x19f/0x220 [wilc1000 884bf126e9e98af6a708f266a8dffd53f99e4bf5]

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.
