[RFC PATCH 1/4] watchdog: hpwdt: Don't disable watchdog on NMI

[Ivan Mironov <mironov.ivan@gmail.com>]

Existing code disables watchdog on NMI right before completely hanging
the system.

There are two problems here:

 * First, watchdog is expected to reset the system in a case of such
   failure, no matter what.
 * Second, this code has no effect if there are more than one watchdog.
