[dpdk-dev] [PATCH V3] table: fix bucket empty logic

[Thierry Herbelot <thierry.herbelot@6wind.com>]

Due to a typo, only 3 out of 4 keys in the bucket of the exact match
table were considered, which can result in valid keys being
incorrectly dropped from the table.

Fixes: d0a00966618ba ("table: add exact match SWX table")
