btrfs: use the same uptodate variable for end_bio_extent_readpage()

In function end_bio_extent_readpage() we call
endio_readpage_release_extent() to unlock the extent io tree.

However we pass PageUptodate(page) as @uptodate parameter for it, while
for previous end_page_read() call, we use a dedicated @uptodate local
variable.

This is not a big deal, as even for subpage cases, either the bio only
covers part of the page, then the @uptodate is always false, and the
subpage ranges can still be merged.

But for the sake of consistency, always use @uptodate variable when
possible.
