fsck: do not complain on detached HEAD.

Browse Source 
Detached HEAD is just a normal state of a repository.  Do not
say anything about it.

Do not give worrying "error:" messages when we let the user know
that the HEAD points at nothing (i.e. yet to be born branch),
nor we do not have any default refs to start following the
objects chain.  Reword them as "notice:".
