Just `memset()` this to `0`.
Without this kamailio segfaults when running `fparam_free_restore()` on a variable that contains transformations immediately after creation, because field `next` of the transformation contains garbage.
In my case this was variable which contained `re.subst` transformation. And below is the top of the backtrace.

ims_charging: fixed check result code at mscc level (#1504)
* ims_charging: fixed check result code at mscc level
according to RFC 4006 the Result-Code in Multiple-Services-Credit-Control AVP is optional.
resume_on_initial_ccr() stops proceeding CCA if no Result-Code in MSCC and goes to error1 even though
the Result-Code on CCR itself is 2001 (SUCCESSFUL)
