ide-atapi: switch to blk_rq_bytes() on do_request() path
After the recent struct request cleanups, blk_rq_bytes() is guaranteed to be valid and is the current total length of the rq's bio. Use that instead of pc->req_xfer in the do_request() path after the command has been queued The remaining usage of pc->req_xfer now is only until we map the rq to a bio. While at it: - remove local caching of rq completion length in ide_tape_issue_pc() Signed-off-by: Borislav Petkov <petkovbb@gmail.com>
