### Description
Kamailio's ims_usrloc_pcscf module fetches all contact informations from location
table at startup.
I noticed that it fails to fetch protocol information. I checked the function which reads
the contact row:
https://github.com/kamailio/kamailio/blob/c3629f877500373028d2c7cdefd976cdd…
I saw that it is read the value as INT. Then checked database table and saw that protocol
field is CHAR(5).
https://github.com/kamailio/kamailio/blob/master/utils/kamctl/mysql/ims_usr…
```
CREATE TABLE `location` (
...
`protocol` char(5) DEFAULT NULL,
...
);
```
The protocol fields needs to be INT in location table as well.
This bug leads to other bugs because protocol information is used in aor_hash calculation.
Best regards

### Troubleshooting
#### Reproduction
Put a record in location table with protocol value as 1.
Set ims_usrloc_pcscf module parameter db_mode as 1.
After kamailio startup, on debug log, protocol information will be seen as a big integer
value.
#### Debugging Data
<!--
If you got a core dump, use gdb to extract troubleshooting data - full backtrace,
local variables and the list of the code at the issue location.
gdb /path/to/kamailio /path/to/corefile
bt full
info locals
list
If you are familiar with gdb, feel free to attach more of what you consider to
be relevant.

```
#### Log Messages
<!--
Check the syslog file and if there are relevant log messages printed by Kamailio, add them
next, or attach to issue, or provide a link to download them (e.g., to a pastebin site).
-->
```
(paste your log messages here)
```
#### SIP Traffic
<!--
If the issue is exposed by processing specific SIP messages, grab them with ngrep or save
in a pcap file, then add them next, or attach to issue, or provide a link to download them
(e.g., to a pastebin site).
-->
```
(paste your sip traffic here)
```
### Possible Solutions
<!--
If you found a solution or workaround for the issue, describe it. Ideally, provide a pull
request with a fix.
-->
The protocol fields can be defined as INT in location table.
