ionic: prevent pci disable of already disabled device

Browse Source 
[ Upstream commit 13943d6c82730a2a4e40e05d6deaca26a8de0a4d ]

If a reset fails, the PCI device is left in a disabled
state, so don't try to disable it again on driver remove.
This prevents a scary looking WARN trace in the kernel log.
