net/qede: refactor Rx and Tx queue setup

This patch refactors Rx and Tx queue setup flow required to allow
odd number of queues to be configured in next patch.

This is the first patch of the series required to fix an issue
where qede port initialization in ovs-dpdk fails due to 1 Rx/Tx queue
configuration. Detailed explanation is given in next patch.
