MDEV-35420 Server aborts while deleting the record in spatial index

Browse Source 
- This issue caused by commit a032f14b342c782b82dfcd9235805bee446e6fe8(MDEV-33559).
In MDEV-33559, matched_rec::block was changed to pointer
and assinged with the help of buf_block_alloc(). But patch
fails to check for the block can be nullptr in
rtr_check_discard_page().

rtr_cur_search_with_match(): Acquire rtr_match_mutex before
creating shadow block for the matched records

rtr_pcur_move_to_next(): Copy the shadow block to page cursor
block under rtr_match_mutex
