search: don't set placewewant when we are just iterating

In the innermost search loop, don't set placewewant, because this loop
is also used for replacing and spell fixing, when we don't really want
to be there: we are just passing through.  Not setting placewewant means
we don't need to save and restore it in those passing-through routines.

The value of placewewant is only relevant when doing cursor movement,
which doesn't happen during replacing nor spell checking, so there is
no need to keep placewewant up to date -- it is set when it matters:
at the end of go_looking().
