lib/vsprintf.c: fix vscnprintf() if @size is == 0
vscnprintf() should return 0 if @size is == 0. Update the comment for it, as @size is unsigned. This change based on the code of commit b903c0b8899b46829a9b80ba55b61079b35940ec ("lib: fix scnprintf() if @size is == 0") moves the real fix into vscnprinf() from scnprintf() and makes scnprintf() call vscnprintf(), thus avoid code duplication.
