[jmorlan] 35049: - Remove some redundant ProcessData == NULL checks - ClientConnectionThread already checks this for every request. - CsrApiCallHandler: Get rid of "Found" variable and just return when the right definition is found. - Make CsrApiCallHandler use the return value from the function (previously unused) to set Request->Status, and trim the now-redundant Request->Status setting from tons of CSR_API functions. - CsrCreateProcess: Don't set shutdown parameters again - already set in Csr

Log:
- Remove some redundant ProcessData == NULL checks - ClientConnectionThread already checks
this for every request.
- CsrApiCallHandler: Get rid of "Found" variable and just return when the right
definition is found.
- Make CsrApiCallHandler use the return value from the function (previously unused) to set
Request->Status, and trim the now-redundant Request->Status setting from tons of
CSR_API functions.
- CsrCreateProcess: Don't set shutdown parameters again - already set in
CsrCreateProcessData.
