scsi: ufs: uapi: Fix SPDX license identifier

Added 'WITH Linux-syscall-note' exception which is the officially assigned
exception identifier for the kernel syscall exception.  This exception
makes it possible to include GPL headers into non GPL code without
confusing license compliance tools.

Fixes: a851b2b (scsi: uapi: ufs: Make utp_upiu_req visible to user space)
