MDEV-21174: Replace mlog_memset() with mtr_t::memset()
Passing buf_block_t helps us avoid calling
mlog_write_initial_log_record_fast() and page_get_page_no(),
and allows us to implement more debug checks, such as
that on ROW_FORMAT=COMPRESSED index pages, only the page header
may be modified by MLOG_MEMSET records.
fseg_n_reserved_pages(): Add a buf_block_t parameter.
