net/sfc: do not skip RSS configuration step on reconfigure

net/sfc: do not skip RSS configuration step on reconfigure

Earlier a patch was made to support change of Rx queue
number. That patch added goto label in wrong place
because reconfiguration with the same number of queues
results in skipping not only queue init but also RSS
settings. If a user configures device with RSS multiqueue
mode and then wants to stop it and reconfigure without RSS,
this change will be ignored and RSS will continue working.

Move the label in the right place and rename it to describe it.
