scsi: sg: add sg_remove_request in sg_common_write
commit 849f8583e955dbe3a1806e03ecacd5e71cce0a08 upstream.
If the dxfer_len is greater than 256M then the request is invalid and we
need to call sg_remove_request in sg_common_write.

Fixes: f930c7043663 ("scsi: sg: only check for dxfer_len greater than 256M")
