mwifiex: do not declare wdev as pointer
wdev is used even after del_virtual_interface handler in cfg80211
in nl80211_post_doit. Since we have freed wdev in handling of
del_virtual_intf, this can result into crash while deleting
interface.
Avoid this be not declaring wdev which part of
mwifiex_private structure but struct wireless_dev type.
