[PATCH net v2] net/qla3xxx: disable the PCI device on remove

[Myeonghun Pak <mhun512@gmail.com>]

ql3xxx_probe() enables the PCI device and balances that reference on
probe failure. However, ql3xxx_remove() releases the mappings and PCI
regions without disabling the device, leaving the enable reference
held after unbind.

Add pci_disable_device() at the end of ql3xxx_remove() to balance the
successful probe's pci_enable_device() call. Keep the existing manual
cleanup and probe error handling unchanged.

This issue was identified during our ongoing static-analysis research while
reviewing kernel code.

    to pcim_enable_device(), as suggested by Simon Horman.
