ChecksumUtil.validateChecksum logs an INFO message inside a "if(LOG.isTraceEnabled())" block.

Noticed this while analysing another potential checksum issue. Despite doing a check for TRACE level, we log an INFO message inside the if block:

if (LOG.isTraceEnabled()) {
      LOG.info("dataLength=" + buf.capacity() + ", sizeWithHeader=" + onDiskDataSizeWithHeader
          + ", checksumType=" + ctype.getName() + ", file=" + pathName + ", offset=" + offset
          + ", headerSize=" + hdrSize + ", bytesPerChecksum=" + bytesPerChecksum);
    }

Uploading a patch that logs a TRACE message and switch to parameterising logging. Since there's no extra computation on the param passing, we shouldn't need the extra if either.
