x86/mm/cpa: Make cpa_data::vaddr invariant

Currently __change_page_attr_set_clr() will modify cpa->vaddr when
!(CPA_ARRAY | CPA_PAGES_ARRAY), whereas in the array cases it will
increment cpa->curpage.

Change __cpa_addr() such that its @idx argument also works in the
!array case and use cpa->curpage increments for all cases.

NOTE: since cpa_data::numpages is 'unsigned long' so should cpa_data::curpage be.
NOTE: after this only cpa->numpages is still modified.
