staging: comedi: adl_pci9118: use CMDF_WAKE_EOS

Replace use of `TRIG_WAKE_EOS` command flag with the new name
`CMDF_WAKE_EOS`.  The numeric value is unchanged.  Also change
diagnostic messages to use "CMDF_WAKE_EOS" instead of "TRIG_WAKE_EOS"
and change the Comedi driver description comment to use "CMDF_WAKE_EOS".
