'pkt_len' is used to interact with a hardware register. It might not
be safe to remove it entirely. Mark it as __maybe_unused instead.
Fixes the following W=1 kernel build warning(s):
drivers/net/ethernet/smsc/smc91x.c: In function ‘smc_tx’:
drivers/net/ethernet/smsc/smc91x.c:706:51: warning: variable ‘pkt_len’ set but
not used [-Wunused-but-set-variable]
