btrfs: cleanup the main loop in btrfs_lookup_bio_sums

Browse source

Introduce a bio_offset variable for the current offset into the bio
instead of recalculating it over and over.   Remove the now only used
once search_len and sector_offset variables, and reduce the scope for
count and cur_disk_bytenr.
