MDEV-24188 Hang in buf_page_create() after reusing a previously freed page
The fix of MDEV-23456 (commit b1009ae5c16697d5eef443cc6a60a74301148c73)
introduced a livelock between page flushing and a thread that is
executing buf_page_create().
buf_page_create(): If the current mini-transaction is holding
an exclusive latch on the page, do not attempt to acquire another
one, and do not care about any I/O fix.
mtr_t::have_x_latch(): Replaces mtr_t::get_fix_count().
dyn_buf_t::for_each_block(const Functor&) const: A new variant.
rw_lock_own(): Add a const qualifier.
