idpf: fix possible vport_config NULL pointer deref in remove

Attempting to remove the driver will cause a crash in cases where

the vport failed to initialize. Following trace is from an instance where

the driver failed during an attempt to create a VF:

[ 1661.543624] idpf 0000:84:00.7: Device HW Reset initiated

[ 1722.923726] idpf 0000:84:00.7: Transaction timed-out (op:1 cookie:2900 vc_op:1 salt:29 timeout:60000ms)
