zapcard: revert buffer length back to 160 (20ms) 

while the smaller buffer length had a positive impact on
ISDN data calls, it breaks yate's handling of SIP/RTP to TDM calls.
Yate will start to emit 16ms packets with a buffer length of 128,
which will lead to broken call audio with many SIP providers.
