fix: prevent subnet from getting permanently stuck when VLAN is not ready (#6352)

Fix two bugs that combine to cause underlay subnets to get permanently
stuck during controller startup when the VLAN is created after the subnet.

Bug 1: In handleAddOrUpdateSubnet, variable shadowing (err :=) and
overwriting (err =) in the VLAN/subnet validation error paths caused
patchSubnetStatus success to zero out the original validation error.
The handler returned nil, making the work queue forget the item instead
of retrying it. Fix by using a separate patchErr variable for the patch
call and using = instead of := for the error wrapping.

Bug 2: handleAddVlan did not re-enqueue subnets that reference the
newly created VLAN. Once a subnet's validation failed and was forgotten
by the queue, no event would trigger it to be reprocessed. Fix by
iterating over subnets at the end of handleAddVlan and adding those
referencing the VLAN back to the addOrUpdateSubnetQueue.
