Do not ask to initialize disks with softraid chunks

Skip chunk devices in the 'Which disk do you wish to initialize?' question.
Touching sd0, e.g. after a root on softraid sd1 install on sd0, will fail.

get_dkdevs_uninitialized() is used once, in interactive installs, right
after root disk setup, iff multiple disks exist.

Tested as part of a bigger diff by a few
OK cheloha
