[PATCH v2 5/8] target/loongarch: Use loongarch_tlb_search_cb in helper_invtlb_page_asid

[Bibo Mao]

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 MTLB.

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