[PATCH v2 1/3] net/sfc: set Rx queue type flags from scratch on queue setup

[Ivan Malov <ivan.malov@arknetworks.am>]

Derive queue type flags from scratch on every queue setup
so that flags left over from a previous configuration do
not persist when an offload is disabled.

Fixes: b8cf5ba549f2 ("net/sfc: support initialising different Rx queue types")
