Reinstate file existence for StoreInHAL={TRUE} case

Detail:
  s/sdcmos - The previous change to remove the filetype check when StoreInHAL={TRUE} also had the side-effect of removing the check for whether the file exists.
  This resulted in the module not terminating itself if the file was absent, and consequently all attempts to write to CMOS would generate a 'file not found' error, causing assorted bits of code to malfunction.
