It is a useful to be able to exercise kmsg_dumper implementations without
requiring a kernel oops or panic.  This commit adds a new reason called
KMSG_DUMP_SOFT, which signifies that the system isn't really going down.

This logic is used in a later commit that introduces the netoops driver.

Notes:

It is also possible that we not introduce KMSG_DUMP_SOFT, and simply overload
the existing KMSG_DUMP_OOPS reason, but I figured that this would be cleaner.
