scsi: bsg: fix buffer overflow in scsi_bsg_uring_cmd()
The bounds checking in scsi_bsg_uring_cmd() does not work because
cmd->request_len is a u32 and scmd->cmd_len is a u16. We check that
scmd->cmd_len is valid but if the cmd->request_len is more than
USHRT_MAX it would still lead to a buffer overflow when we do the
copy_from_user().
