Add pr_fmt() to kernel/crash_core.c to add the module name to debugging message printed as prefix.
And also add prefix 'crashkernel:' to two lines of message printing code in kernel/crash_reserve.c. In kernel/crash_reserve.c, almost all debugging messages have 'crashkernel:' prefix or there's keyword crashkernel at the beginning or in the middle, adding pr_fmt() makes it redundant.
