      liquidio: fix possible eeprom format string overflow · 56c0da49

      gcc reports that the temporary buffer for computing the
      string length may be too small here:

        len = sprintf(buf, "boardname:%s serialnum:%s maj:%lld min:%lld\n",
      
      This extends it to 192 bytes, which is certainly enough. As far
      as I could tell, there are no other constraints that require a specific
      maximum size.

      The current code is safe, but making the string a little longer
      is harmless and lets gcc see that it's ok.

      This probably can't happen, but it can't hurt to make it long
      enough for the theoretical limit.

      There is a hard limit in place that makes the number at most two
      digits, so the code is fine. This changes it to use snprintf()
      to truncate instead of overflowing, which shuts up that warning.

      While we know that the port number is small, there is no harm in
      making the format string two bytes longer to avoid the warning.
