Previously, the range of log level is from 1 to 6, and the TRACE
level and FATAL level are not used, therefore, let's remove these
unused log levels and update the kdump sysconfig accordingly.
Nowadays it has only four log levels: error(1), warn(2), info(3)
and debug(4). We have to remap the numeric log level to the logger
priority or syslog log level, which is finished in kdump-logger.sh
module, it is invisible for user.
In addition, kdump uses the different options to control the log
levels for the first kernel and the second kernel.
