xen/gntdev: don't dereference a null gntdev_dmabuf on allocation failure
Currently when the allocation of gntdev_dmabuf fails, the error exit
path will call dmabuf_imp_free_storage and causes a null pointer
dereference on gntdev_dmabuf. Fix this by adding an error exit path
that won't free gntdev_dmabuf.
Detected by CoverityScan, CID#1472124 ("Dereference after null check")
Fixes: bf8dc55b1358 ("xen/gntdev: Implement dma-buf import functionality")
