It returns the number of vectors allocated when successful, so check for
a negative error only.

Cleans up the IRQ management code a lot, including removing a lot of

Move PCI_VENDOR_ID_VMWARE from device-specific files to pci_ids.h.
It is useful to always have access to it, especially when accessing
subsystem_vendor_id on emulated devices.

Removes DEFINE_PCI_DEVICE_TABLE from drivers/misc/genwqe/card_base.c,
drivers/misc/genwqe/card_base.c, and drivers/misc/vmw_vmci/vmci_guest.c
in preferance of a "real" structure definition.

As result of deprecation of MSI-X/MSI enablement functions
pci_enable_msix() and pci_enable_msi_block() all drivers
using these two interfaces need to be updated to use the
new pci_enable_msi_range() or pci_enable_msi_exact()
and pci_enable_msix_range() or pci_enable_msix_exact()
interfaces.

When host capabilities check failed or when we were unable to register doorbell
bitmap we were forgetting to set error code and were returning 0 which would
make upper layers believe that probe was successful.

free_irq() expects the same device identity that was passed to
corresponding request_irq(), otherwise the IRQ is not freed.

This patch adds support for virtual IOMMU to the vmci module. We switch
to DMA consistent mappings for guest queuepair and doorbell pages that
are passed to the device. We still allocate each page individually,
since there's no guarantee that we'll get a contiguous block of physical
for an entire queuepair (especially since we allow up to 128 MiB!).
Also made the split between guest and host in the kernelIf struct much
clearer. Now it's obvious which fields are which.

I'm an idiot. The context ID can be a really large unsigned number, which
means it'll appear negative as an int. So actually the right fix here is just
to set it regardless of the returned value (but only for this particular
hypercall; normally we would check it).

vmci_send_datagram() returns an int, with negative values indicating failure.
But we store it locally in a u32, which makes comparison of >= 0 useless.
Fixed to use an int.
