Make "SD Card removed" notification dismissible if the removed SD Card is not the primary storage

The Galaxy S uses the "external SD Card" as the extended storage
and it the notification should be dismissible as it's okay not

Additionally, this patch also not hide the USB storage mount dialog
if the removed storage is not the primary storage
