jdi_panel_init() is never called in atomic context.

Despite never getting called from atomic context, jdi_panel_init() calls mdelay() to busily wait. This is not necessary and can be replaced with usleep_range() and msleep() to avoid busy waiting.

This is found by a static analysis tool named DCNS written by myself. And I also manually check it.
