dc_number is a global variable indicating the currently displayed dive on desktop. It makes no sense on mobile, since multiple profiles can be active at the same time. Therefore, the profile code should not access this global, but use the dc number that is passed in. This removes the last access. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
