scsi: scsi_debug: Fix a locking bug in resp_write_same()
If fetch_to_dev_buffer() fails in resp_write_same(), the function jumps
to 'out' without releasing the data write lock acquired earlier via
sdeb_data_write_lock(). Jump to 'unlock' instead so that
sdeb_data_write_unlock() is called on the error path. This bug has been
discovered by building the scsi_debug driver with Clang and modified
lock context annotations. The modified lock context annotations are
available in patch "scsi: scsi_debug: Improve lock context annotations".
