Title: #455: mmap_cache: make checks independent of input size

mzidek-rh commented:
Hi @fidencio ,
at first look I also thought covscan found an issue here, but looking closer 
this seems to be a false positive match. Few lines above the check that you 
added is already a check if the body of message is null terminated, so memchr 
here will never return NULL (it has to return at least pointer to the last '\0' 
in the message).
