When PMP entry overlap part of the page, we'll set the tlb_size to 1, which
will make the address in tlb entry set with TLB_INVALID_MASK, and the next
access will again go through tlb_fill.However, this way will not work in
tb_gen_code() => get_page_addr_code_hostp(): the TLB host address will be
cached, and the following instructions can use this host address directly
which may lead to the bypass of PMP related check.
