[PATCH 1/4] io_uring/rsrc: avoid assigning buf table on failure

[Pavel Begunkov <asml.silence@gmail.com>]

The fail path of io_sqe_buffers_register() assigns ->buf_table just to
implicitly pass it into io_sqe_buffers_unregister(). Be more explicit
by using io_rsrc_data_free() for destruction and passing the table to it
directly.
