ath9k: work around false-positive gcc warning
gcc-10 shows a false-positive warning with CONFIG_KASAN:
drivers/net/wireless/ath/ath9k/dynack.c: In function 'ath_dynack_sample_tx_ts':
include/linux/etherdevice.h:290:14: warning: writing 4 bytes into a region of size 0 [-Wstringop-overflow=]
290 | *(u32 *)dst = *(const u32 *)src;
| ~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~
Until gcc is fixed, work around this by using memcpy() in place
of ether_addr_copy(). Hopefully gcc-11 will not have this problem.
