io_uring/rsrc: remove unused constants

IO_NODE_ALLOC_CACHE_MAX has been unused since commit fbbb8e991d86
("io_uring/rsrc: get rid of io_rsrc_node allocation cache") removed the
rsrc_node_cache.

IO_RSRC_TAG_TABLE_SHIFT and IO_RSRC_TAG_TABLE_MASK have been unused
since commit 7029acd8a950 ("io_uring/rsrc: get rid of per-ring
io_rsrc_node list") removed the separate tag table for registered nodes.
