[PATCH] fixup! environment: prefer non-removable over removable devices for autoprobe

Instead of ad-hoc determination in an inline function in the header, let
every user decide for itself, it the device is removable or not.
This changes the implementation slightly: SD-Cards with the
non-removable device tree property are now reported as such to the block
layer, whereas before, they were always removable.
