Tomohiro Kusumi f0ce0436aa Correct snprintf() size argument
The size argument of snprintf(3) in glibc and snprintf() in Linux
kernel includes trailing \0, as snprintf(3) man page explains it as
"write at most size bytes (including the trailing null byte ('\0'))",
i.e. snprintf() can just take buffer size.

e.g. For snprintf() in module/zfs/zfs_ctldir.c, a buffer size is
MAXPATHLEN, and a caller is passing MAXPATHLEN to snprintf(), so size
should just be `path_len` to do what the caller is trying to do.
