patch with mallocarray(9), printf(9) and a single fallback block
Attached is the latest patch with a single fallback block which is executed
depending on the return values from mallcoarray(... | M_NOWAIT) calls. The code
sets the value of respective variable that is passed to mallocarray(9) rather
than directly using PH_HASHSIZ in the mallocarray(9) call.
I tried the patch on a 512MB VM running FreeBSD-12.0CURRENT and verified that
PF initialisation went okay. A log message indicating the memory allocation
issue is present in /var/log/messages (and in the console).
