Add a missing clear_current_lookup() call in recv_done()

The error code path handling the `ISC_R_CANCELED` code lacks a
`clear_current_lookup()` call, without which dig hangs indefinitely
when handling the error.

Add the missing call to account for all references of the lookup so
it can be destroyed.
