Subject: [PATCH] src/bandwidthd.h: fix build with gcc 10

Remove SubnetTable[SUBNET_NUM] and IpTable[IP_NUM] from bandwidthd.h as
they are already in bandwidthd.c otherwise the build with gcc 10 will
fail on:

/home/buildroot/autobuild/instance-2/output-1/host/bin/arm-buildroot-linux-gnueabihf-gcc  -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64  -Os     -o bandwidthd bandwidthd.o graph.o extensions.o sqlight.o parser.o lexer.o pgsql.o  -lpcap -lgd -lm -lresolv  -L/home/buildroot/autobuild/instance-2/output-1/host/bin/../arm-buildroot-linux-gnueabihf/sysroot/usr/lib -lpng16 -lz  -L/home/buildroot/autobuild/instance-2/output-1/host/arm-buildroot-linux-gnueabihf/sysroot/usr/bin/../../../../arm-buildroot-linux-gnueabihf/sysroot/usr/lib/.libs -lnl-genl-3 -lnl-3
