[XFS] Prevent buffer overrun in cmn_err().
The message buffer used by cmn_err() is only 256 bytes and some CXFS messages were exceeding this length. Since we were using vsprintf() and not checking for buffer overruns we were clobbering memory beyond the buffer. The size of the buffer has been increased to 1024 bytes so we can capture these larger messages and we are now using vsnprintf() to prevent overrunning the buffer size.
