MDEV-23399 fixup: Remove double-free of a buffer page

In commit 7cffb5f we changed the
interface of buf_page_create() so that the free_block is allocated
by the caller. Both calls to buf_LRU_block_free_non_file_page()
should have been removed.

This caused an assertion failure 'block->page.state() == BUF_BLOCK_MEMORY'
in buf_LRU_block_free_non_file_page().

The bug only affected ROW_FORMAT=COMPRESSED pages.
