MDEV-7762 InnoDB: Failing assertion: block->page.buf_fix_count > 0 in buf0buf.ic line 730
Analysis: debug only assertion I_S function (IS is XtraDB feature) is calling
buf_block_get_frame on any page it reads, which debug-asserts that the page is
buffer-fixed, which is not the case in I_S query.
Fixed by holding the buffer page mutex while the fields are read directly.
which is NOT applied to percona code 5.5 for sure.
