nfs: Remove unneeded checking of the return value from scnprintf

The return value from scnprintf always less than the buffer length.
So, result >= len always false. This patch removes those checking.

int vscnprintf(char *buf, size_t size, const char *fmt, va_list args)
{
        int i;

i = vsnprintf(buf, size, fmt, args);

if (likely(i < size))
return i;
if (size != 0)
return size - 1;
return 0;
}
