Subject: [PATCH] net/qede: fix to reject config with no Rx queue

[ upstream commit e60644c4420c47fa196c0c947a6c6e5891d167d0 ]

The qede firmware expects minimum one RX queue to be created, otherwise
it results in firmware exception. So a check is added to prevent that.

Fixes: ec94dbc57362 ("qede: add base driver")
