[dpdk-dev] [PATCH v3 20/60] common/sfc_efx/base: move EvQ create generic checks

[Andrew Rybchenko <arybchenko@solarflare.com>]

There is no point to duplicate these generic checks in NIC family
specific handlers.

As the side effect it fixes bug with incorrect interrupt moderation
settings silently ignored on event queue create on Siena.
