win: invalidate reg_ignore properly when destroying window

Browse Source 
reg_ignore_valid marks the validity of the reg_ignore of the windows
BENEATH the current window. That is, set `w->reg_ignore_valid = false`
doesn't invalidate `w->reg_ignore`.

When destroying window `w`, we need to invalidate all reg_ignore beneath
`w`. So it is not enough to just set `w->next->reg_ignore_valid =
false`, we also need to invalidate `w->next->reg_ignore`.

Yes, this variable name is confusing. Will be changed in the future.
