staging: line6: drop midi_postprocess flag
It is no longer necessary to trigger on MIDI transmit messages that will
change the state of the device since:
1. We've dropped the midi_postprocess sysfs attr in a previous commit so
it is not possible to activate this feature anymore.
2. The other sysfs attrs that could inspect the state after a dump
request have been dropped.
Therefore we can safely remove this dead code.
