busybox: fix mount issue

When the mount command is not given the filesystem type to mount, then
it will try all the known filesystems. However, when a filesystem is not
supported by the kernel, the mount function call will return ENODEV.

The following patch, ecd90bc6aa63da2aef2513ac090d4b426b2b719c,
introduced a problem because it bailed out on ENODEV too. Instead it should
have only bailed out on ENOMEDIUM.
