ethtool: fix ethtool msg len calculation for pause stats
[ Upstream commit 1aabe578dd86e9f2867c4db4fba9a15f4ba1825d ]
ETHTOOL_A_PAUSE_STAT_MAX is the MAX attribute id,
so we need to subtract non-stats and add one to
get a count (IOW -2+1 == -1).
Otherwise we'll see:
ethnl cmd 21: calculated reply length 40, but consumed 52
