Send SBC frames if output buffer is nearly full.
This is to address an A2DP issue seen with the Mazda carkit, where A2DP audio
cannot be played. The MTU size (8200) requested by this carkit is much greater
than the output buffer size (2048) allocated by the Bluez A2DP profile. The
output buffer being full is giving an SBC encode error. This patch checks for
the buffer full condition.
