#### Description <!-- Describe your changes in detail --> Currently Kamailio does not update expiry when assigning a value to an expired cell if htable's `updateexpire` equals `0`. So expired cells aren't usable as long htable timer cleans up these cells. Reproduction 1: ``` #!KAMAILIO

listen=udp:127.0.0.1:9999

log_stderror=yes

loadmodule "xlog.so" loadmodule "pv.so" loadmodule "sl.so" loadmodule "htable.so"

modparam("htable", "htable", "foo=>autoexpire=1;updateexpire=0;initval=0")

request_route { if ($sht(foo=>bar) == $null) { xlog("it's null, init it\n"); } $sht(foo=>bar) = $sht(foo=>bar) + 1; xlog("$Ts value $sht(foo=>bar)\texpire $shtex(foo=>bar)\n"); sl_send_reply("200", "Hello"); } ``` output: ``` 0(787651) ERROR: <script>: 1736855046 value 1 expire 1 0(787651) ERROR: <script>: 1736855046 value 2 expire 1 0(787651) ERROR: <script>: 1736855047 value 3 expire 0 0(787651) ERROR: <script>: 1736855048 value 0 expire 4294967295 0(787651) ERROR: <script>: 1736855048 value 0 expire 4294967295 0(787651) ERROR: <script>: 1736855049 value 0 expire 4294967294 0(787651) ERROR: <script>: 1736855050 value 0 expire 4294967293 SNIP expire decreases while value stays 0 0(787651) ERROR: <script>: 1736855066 value 1 expire 1 0(787651) ERROR: <script>: 1736855066 value 2 expire 1 0(787651) ERROR: <script>: 1736855067 value 3 expire 0 ``` Reproduction 2: ``` #!KAMAILIO
