Fix a race between a reader swapping a new reader page into the ring-buffer from rb_get_reader_page() and the rb_check_pages() check invoked at the end of the resize operation in ring_buffer_resize().
Note that a similar problem with rb_check_pages() being executed with concurrent readers looks to exist for ring_buffer_subbuf_order_set() too. I plan to tackle it in a separate series.
