memory/alloc: Use SCCalloc instead of malloc/memset

[jlucovsky]

Replace SCMalloc/memset with SCCalloc

There are many places that use the following pattern:

     mem = SCMalloc(sizeof(foo));
     if (mem) {
        memset(&mem, 0, sizeof(foo));
    }

These can all be replaced by using SCCalloc which returns 0-filled memory.

Describe changes:

• Changed SCMalloc followed by memset to SCCalloc

Provide values to any of the below to override the defaults.

To use a pull request use a branch name like pr/N where N is the
pull request number.

Alternatively, SV_BRANCH may also be a link to an
OISF/suricata-verify pull-request.

Seems we're in a draft/non-draft situation... :)

I moved it to non-draft because the CI checks were green.

However, we can leave it in draft form until the release branch has been created.

Was referring to the subject still saying "DRAFT" :)
