[ion] 24463: - Initialize the registry in one shot, and allow it to fail and do the associated CONFIG_INIT_FAILED bugcheck. - Initialize Io in one shot, with IoInitSystem. - Locate the system DLL a bit later, since on the boot CD this creates a small incompatibility due to the wrong path being in use.

Log:
- Initialize the registry in one shot, and allow it to fail and do the associated
CONFIG_INIT_FAILED bugcheck.
- Initialize Io in one shot, with IoInitSystem.
- Locate the system DLL a bit later, since on the boot CD this creates a small
incompatibility due to the wrong path being in use.
