btrfs: factor out helper adding a page to bio

Browse source

Factor out adding a page to a bio from submit_extent_page().  The page
is added only when bio_flags are the same, contiguous and the added page
fits in the same stripe as pages in the bio.

Condition checks are reordered to allow early return to avoid possibly
heavy btrfs_bio_fits_in_stripe() calling.
