### Description

Recently I upgraded kamailio to 5.4.2 using the dlgs module. No matter how many calls I make, the dlgs_count() and dlgs_tags_count() always return 1. After viewing the source code, I found the following bugs

### Troubleshooting

#### Reproduction

dlgs_init($fu,$tu,"data"); dlgs_update(); dlgs_count("any","eq","1"); and then make several calls, the dlgs_count always return 1.

### Possible Solutions

I find the `ki_dlgs_count` functions always return 1;  I modified the retrun value = 10086, then the `dlgs_count` always return 10086 ! ! I modified the return value = dlgs_count(msg, vfield, vop, vdata); then I found the dlgs_count always return 0; obviously there is still something wrong. then I run the dlgs_ht_dbg() in the dlgs_count (dlgs_records.c) and get some useful dbg log as above. as the picture shows，the slots[i].astats.c_init is always 0 or -1. I think maybe c_init is not initialized to 1 when dlgs_init . and I add the c_init's initial logic in the dlgs_add_items() then everything is fine !
