media: atomisp: Fix up the open v load race

Browse source

Date: Mon, 06 Nov 2017 23:36:36 +0000

This isn't the ideal final solution but it stops the main problem for now
where an open (often from udev) races the device initialization and we try
and load the firmware twice at the same time. This needless to say doesn't
usually end well.
