Don't show links to media-new.php on mobile devices
|Reported by:||SergeyBiryukov||Owned by:|
"Media → Add New" link in admin menu is hidden for mobile devices:
However, there are two more links on Media Library screen (Add New) and in the Toolbar (New → Media).
Since wp-admin/media-new.php has a check against mobile devices, those links lead to a blank screen. We should remove them consistently and probably print an error message if a user somehow ends up on that screen anyway.
