Subject: [PATCH] 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.
