Handle a few more cellSaveData errors

Browse Source 
* Check directory existence if setParam is NULL (dont create directory)
* Fix mask for reCreateMode
* Check a few setParam fields including reserved buffers.
* Fix sizeKb when the dir is empty except from PARAM.SFO
* Fix error checking when CELL_SAVEDATA_RECREATE_YES is specified but setParam is NULL (Doesnt do anything, simply errors)
