target/loongarch: Use loongarch_tlb_search_cb in helper_invtlb_page_asid

With function helper_invtlb_page_asid(), currently it is to search
TLB entry one by one. Instead STLB can be searched at first with hash
method, and then search MTLB with one by one method

Here common API loongarch_tlb_search_cb() is used in function
helper_invtlb_page_asid()
