wangmengyang e9e3bc492b component/bt: bugfix that A2DP sink device can be connected by another A2DP sink device 
In pevious implementation, A2DP sink will register an A2DP source Stream End Point(SEP) although the SEP is not\
supposed to be used. Now remove the unused SEP for source so that only one role of A2DP can be supported at one
time. Service record in local SDP server only includes at most one service for A2DP sink role or source
