cfg802154: pass name_assign_type to rdev_add_virtual_intf()
This code is based on commit 6bab2e19c5ffd
("cfg80211: pass name_assign_type to rdev_add_virtual_intf()")
This will expose in sysfs whether the ifname of a IEEE-802.15.4
device is set by userspace or generated by the kernel.
We are using two types of name_assign_types
o NET_NAME_ENUM: Default interface name provided by kernel
o NET_NAME_USER: Interface name provided by user.
