Subject: wireless: use eth_hw_addr_set() for dev->addr_len cases
Patch-mainline: v5.16-rc1
Git-commit: 8fac27fbc80ecdb22c2dd001e9bb0684eed55c01
References: jsc#PED-1565

Convert all WiFi drivers from memcpy(... dev->addr_len)
to eth_hw_addr_set():

  @@
  expression dev, np;
  @@
  - memcpy(dev->dev_addr, np, dev->addr_len)
  + eth_hw_addr_set(dev, np)

Manually checked the netdevs are allocated with alloc_etherdev(),
so dev->addr_len must be equal to ETH_ALEN.
