pstore: Populate pstore record->time field
The current time will be initially available in the record->time field for all pstore_read() and pstore_write() calls. Backends can either update the field during read(), or use the field during write() instead of fetching time themselves. Signed-off-by: Kees Cook <keescook@chromium.org>
