rGf3c3db35d545: ufshci: validate the CDB before allocating a request

Summary

The CDB pointer and length checks depend only on the CCB, so perform
them before allocating and initializing the request. This avoids a
wasted allocation for invalid CCBs on the I/O path and removes one
request-free error path.
