hal: fix to set tty mode properly

If set parameters API called with key "tty_mode" and
MULTI_VOICE_SESSION_ENABLED flag is not enabled then tty mode is
not executed because voice_extn_set_parameters returns error(-ENOSYS).
Fix by ignore -ENOSYS return code for voice_extn_set_parameters
and voice_extn_compress_voip_set_parameters.
