s390/dasd: Return BLK_STS_INVAL for EINVAL from do_dasd_request
Currently, if CCW request creation fails with -EINVAL, the DASD driver
returns BLK_STS_IOERR to the block layer.
This can happen, for example, when a user-space application such as QEMU
passes a misaligned buffer, but the original cause of the error is
masked as a generic I/O error.
This patch changes the behavior so that -EINVAL is returned as
BLK_STS_INVAL, allowing user space to properly detect alignment issues
instead of interpreting them as I/O errors.
