target/loongarch: Fix helper_lddir() a CID INTEGER_OVERFLOW issue

When the lddir level is 4 and the base is a HugePage, we may try to put value 4
into a field in the TLBENTRY that is only 2 bits wide.

Fixes: Coverity CID 1547717
Fixes: 9c70db9a43388 ("target/loongarch: Fix tlb huge page loading issue")
