[Crash-utility] [PATCH v5 3/6] Extend symname_hash_search with hash table select
Previously symname_hash_search can only search symbols from kernel's
symname_hash. This patch add hash table pointer as parameter for
symname_hash_search. Thus symname_hash_search can be used both for
symname_hash and mod_symname_hash searching.
