btrfs: remove unused variable bio_offset from end_bbio_data_read()
The variable @bio_offset was introduced in commit 7ffd27e378d2 ("btrfs:
pass bio_offset to check_data_csum() directly"), when we are still using
the same endio function for both data and metadata.
Later we had several changes to data and metadata endio functions:
- Data verification is handled by btrfs bio layer
- Split data and metadata endio paths
Now for data path we no longer do any verification in
end_bbio_data_read(), as the verification is handled by btrfs bio layer
already.
Thus there is no need for such bio_offset variable.
