MdeModulePkg UfsPassThru: ASSERT if params are NULL in SignalCallerEvent 

In function SignalCallerEvent(), 'Private' and 'TransReq' are dereferenced
before NULL checking.

Since the function assumes that both 'Private' and 'TransReq' passed in
are not NULL pointer, this commit will add an ASSERT to make sure the
above assumption is satisfied.
