btrfs-progs: read_tree_block() and read_node_slot() cleanup.
Allow read_tree_block() and read_node_slot() to return error pointer.
This should help caller to get more specified error number.
For existing callers, change (!eb) judgmentt to
(!extent_buffer_uptodate(eb)) to keep the compatibility, and for caller
missing the check, use PTR_ERR(eb) if possible.
