[PATCH v2] powernv/opal: Handle OPAL_WRONG_STATE error from OPAL fails

Added check for OPAL_WRONG_STATE error code returned from OPAL.
Currently Linux flashes "unexpected error" over console for this
error. This will avoid throwing such message and return I/O error
for such OPAL failures.

Changes in v2:
 - Added log message indicating sleeping/offline core
