crash: add prefix for crash dumping messages
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.
