Fix coverity scan issue: uninitialized scalar variable

[Description]
Issue type: uninitialized scalar variable

[Root Cause]
In function bta_av_rc_msg(), av.remote_rsp.len and av.remote_rsp.p_data are uninitialized if this VENDOR cmd is not implemented by peer.
While in function handle_rc_vendorunique_rsp(), p_remote_rsp->len may be greater than 0 and call osi_free_and_reset()

[Solution]
Initialize the len and p_data.
Adding code to judge this case, avoid free null pointer.
