fm10k: reset max_queues on init_hw_vf failure
VF drivers must detect how many queues are available. Previously, the driver assumed that each VF has at minimum 1 queue. This assumption is incorrect, since it is possible that the PF has not yet assigned the queues to the VF by the time the VF checks. To resolve this, we added a check first to ensure that the first queue is infact owned by the VF at init_hw_vf time. However, the code flow did not reset hw->mac.max_queues to 0. In some cases, such as during reinit flows, we call init_hw_vf without clearing the previous value of hw->mac.max_queues. Due to this, when init_hw_vf errors out, if its error code is not properly handled the VF driver may still believe it has queues which no longer belong to it. Fix this by clearing the hw->mac.max_queues on exit due to errors. Signed-off-by:Jacob Keller <jacob.e.keller@intel.com> Reviewed-by:
