    tests: Usage a single allocation for test_ghash_gvalue_return
    
    Use a single static allocation for the hash created in regress_test_ghash_gvalue_return().
    This function is explicitly marked as returning the hash with transfer-none
    and doesn't need to re-create the hash each call.
