We added this for a special case that doesn't exist on Linux. Remove
the non-blocking/pinned queuepair code and simplify the driver in
preparation for adding virtual IOMMU support.

Right now we use vmalloc()/alloc_page() for our guest queuepair pages
and then do a virt_to_phys() before passing them down to the device.
That's not going to work if DMA remapping is enabled, since the IOMMU
has no idea about the mappings. Switch to pci_alloc_consistent()
instead. We still
We can't just do virt_to_phys() on memory that we pass to the device and
expect it to work in presence of a virtual IOMMU. We need to add IOMMU
mappings for such DMAs to work correctly. Fix that with
pci_alloc_consistent() where possible, or pci_map_single() where the
mapping is short-lived or

memcpy_fromiovec is moved from net/core/iovec.c to lib/iovec.c.
linux/uio.h provides the declaration for memcpy_fromiovec.
Include linux/uio.h instead of inux/socket.h for it.
