srsenb: remove QAM256 related options in RRC Connection Reconfig 

this part of the RRC connection reconfig has caused issue for some
newer phones like the Iphone X, One Plus 6T.
The phone would receive the message but not respond with a reconfig
complete.

The patch fixes this issue by disabling QAM-256 support altogether.
