[PATCH 4.14 059/217] net: hamradio: use eth_broadcast_addr

From: Stefan Agner <stefan@agner.ch>

[ Upstream commit 4e8439aa34802deab11cee68b0ecb18f887fb153 ]

The array bpq_eth_addr is only used to get the size of an
address, whereas the bcast_addr is used to set the broadcast
address. This leads to a warning when using clang:
drivers/net/hamradio/bpqether.c:94:13: warning: variable 'bpq_eth_addr' is not
needed and will not be emitted [-Wunneeded-internal-declaration]
static char bpq_eth_addr[6];
^

Remove both variables and use the common eth_broadcast_addr
to set the broadcast address.
