btrfs: remove the alignment checks in end_bbio_data_read()

end_bbio_data_read() checks that each iterated folio fragment is aligned
and justifies that with block drivers advancing the bio.  But block
driver only advance bi_iter, while end_bbio_data_read() uses
bio_for_each_folio_all() to iterate the immutable bi_io_vec array that
can't be changed by drivers at all.

Furthermore btrfs has already did the alignment check of the file
offset inside submit_one_sector(), and the size is fixed to fs block
size, there is no need to re-do the alignment check again inside the
endio function.

So just remove the unnecessary alignment check along with the incorrect
comment.
