MINOR: buffer: remove the check for output on b_del()
b_del() is used in :
- mux_h2 with the demux buffer : always processes input data
- checks with output data though output is not considered at all there
- b_eat() which is not used anywhere
- co_skip() where the len is always <= output
Thus the distinction for output data is not needed anymore and the
decrement can be made inconditionally in co_skip().
