[PATCH net-next] net: ovs: fix ovs_drop_reasons error

[Menglong Dong]

I'm sure if I understand it correctly, but it seems that there is
something wrong with ovs_drop_reasons.

ovs_drop_reasons[0] is "OVS_DROP_LAST_ACTION", but
OVS_DROP_LAST_ACTION == __OVS_DROP_REASON + 1, which means that
ovs_drop_reasons[1] should be "OVS_DROP_LAST_ACTION".

Fix this by initializing ovs_drop_reasons with index.
