vdpa: Remove duplicate vdpa UAPI header file

vdpa header file is already present in the tree at
vdpa/include/uapi/linux/vdpa.h and used by vdpa/vdpa.c.

As we discussed in thread [1] vdpa header comes from a different
tree, similar to rdma subsystem. Hence remove the duplicate vdpa
UAPI header file.
