io_uring/rsrc: get rid of the empty node and dummy_ubuf
The empty node was used as a placeholder for a sparse entry, but it
didn't really solve any issues. The caller still has to check for
whether it's the empty node or not, it may as well just check for a NULL
return instead.
The dummy_ubuf was used for a sparse buffer entry, but NULL will serve
the same purpose there of ensuring an -EFAULT on attempted import.
Just use NULL for a sparse node, regardless of whether or not it's a
file or buffer resource.
