ksz884x: don't copy too much in netdev_set_mac_address()

[ Upstream commit 716af4abd6e6370226f567af50bfaca274515980 ]

MAX_ADDR_LEN is 32.  ETH_ALEN is 6.  mac->sa_data is a 14 byte array, so
the memcpy() is doing a read past the end of the array.  I asked about
this on netdev and Ben Hutchings told me it's supposed to be copying
ETH_ALEN bytes (thanks Ben).
