bnxt_en: don't disable an already disabled PCI device

Browse Source 
If device is already disabled in reset path and PCI io error is
detected before the device could be enabled, driver could
call pci_disable_device() for already disabled device. Fix this
problem by calling pci_disable_device() only if the device is already
enabled.
