Description
During MDEV-27557 testing we found the following crash:
#2 0x000055cbfd573981 in ib::fatal::~fatal (this=0x27936b9ce500, __in_chrg=<optimized out>)

buf_page_decrypt_after_read() does decompression only if node.space->is_compressed() && buf_page_is_compressed(dst_frame, flags) condition is true. For our case node.space->is_compressed() returns false as both FSP_FLAGS_FCRC32_GET_COMPRESSED_ALGO() and FSP_FLAGS_HAS_PAGE_COMPRESSION() are false. The space flags is 0x16. What means the space is not compressed. But the 15-th bit of FIL_PAGE_TYPE is set, what means the full_crc32 page is compressed, i.e. buf_page_is_compressed(dst_frame, flags) should return true.
So we have compressed page on non-compressed space. The question is how is it possible?
