HWPOISON: Clean up PR_MCE_KILL interface
While writing the manpage I noticed some shortcomings in the
current interface.
- Define symbolic names for all the different values
- Boundary check the kill mode values
- For symmetry add a get interface too. This allows library
code to get/set the current state.
- For consistency define a PR_MCE_KILL_DEFAULT value
