Fix eth_hw_addr_set() definition for compatibility with stable branches

Browse Source 
eth_hw_addr_set() was added in Linux 5.15 but has now been backported
to 4.19.291, 5.4.251, and 5.10.188.  This currently results in build
failure for these stable branches.

There's no simple way to test for the addition of this function since
LINUX_VERSION_CODE limits version components to 255.

Work around this by defining an inline function rtw_eth_hw_addr_set()
and a macro eth_hw_addr_set().  This effectively shadows any
backported definition of the eth_hw_addr_set() function without any
conflict.
