ibmvnic: Do not process device remove during device reset
The ibmvnic driver does not check the device state when the device
is removed. If the device is removed while a device reset is being
processed, the remove may free structures needed by the reset,
causing an oops.
Fix this by checking the device state before processing device remove.
