MDEV-23973 Change buffer corruption when reallocating an recently freed page

Browse source 
After commit abb678b618
(a follow-up fix to MDEV-19514 to prevent potential hangs)
and MDEV-23399, the probability for hitting a dormant bug
that is related to MDEV-19514 was increased.

buf_page_create(): Call ibuf_merge_or_delete_for_page() also
when reusing a previously freed page.
