Subject: [PATCH] net: ethernet: mscc: fix missing brace warning for old compilers

For older versions of gcc, the array = {0}; will cause warnings:

drivers/net/ethernet/mscc/ocelot_vcap.c: In function 'is1_entry_set':
drivers/net/ethernet/mscc/ocelot_vcap.c:755:11: warning: missing braces around initializer [-Wmissing-braces]
    struct ocelot_vcap_u16 etype = {0};
           ^
drivers/net/ethernet/mscc/ocelot_vcap.c:755:11: warning: (near initialization for 'etype.value') [-Wmissing-braces]
