LU-16433 llite: check vvp_account_page_dirtied

This patch removes duplicated codes from vvp_set_pagevec_dirty()
and check vvp_account_page_dirtied to determine if falling back
to call __set_page_dirty_nobuffers().

HAVE_ACCOUNT_PAGE_DIRTIED_EXPORT also needs to be checked because
vvp_account_page_dirtied is not defined if account_page_dirtied
is exported.
