scsi: qla2xxx: don't disable a not previously enabled PCI device

commit ddff7ed4 upstream.

When pci_enable_device() or pci_enable_device_mem() fail in
qla2x00_probe_one() we bail out but do a call to
pci_disable_device(). This causes the dev_WARN_ON() in
pci_disable_device() to trigger, as the device wasn't enabled
previously.

So instead of taking the 'probe_out' error path we can directly return
*iff* one of the pci_enable_device() calls fails.

Additionally rename the 'probe_out' goto label's name to the more
descriptive 'disable_device'.
