UIO base driver should only free_irq that it has requested.
UIO supports drivers without interrupts (irq == 0) or custom handlers.

This fixes warnings like:

WARNING: CPU: 1 PID: 5478 at kernel/irq/manage.c:1244 __free_irq+0xa9/0x1e0()
Trying to free already-free IRQ 0

This reverts commit 4d8beff2ae07fad85d723b4cdf704b05f0ed4794.

It causes build warnings, and it's incorrect as we do write to this
structure.

Separate irq request/free from the device lifecycle.
After device unregister the parent module can call pci_disable_msi.
>From the PCI MSI how to:

"Before calling this function, a device driver must always call free_irq()
on any interrupt for which it previously called request_irq().
Failure to do so results in a BUG_ON(), leaving the device with
MSI enabled and thus leaking its vector."

So we need to separately free the irq at unregister to allow the device
to be kept around in the case of it still having open FDs.

This driver provides UIO access to memory of a peripheral connected
to the Freescale enhanced local bus controller (eLBC) interface

If uio_register_device() fails in probe(), it breaks off initialization,
deallocates all resources, but returns zero.

The patch adds proper error code propagation.
