btio: actually try to enable MTU auto-tuning A "0" for the input MTU passed to the underlying socket is supposed to indicate that its value should be determined by the L2CAP layer. However, the current code treats a zero imtu just as if there is nothing to change. Introduce rework the code to indicate that the zero imtu is explicitly requested by the caller for the purpose of auto-tuning and -1 is used as not set value. Found by Linux Verification Center (linuxtesting.org). Fixes: ae5be371a9f5 ("avdtp: Enable MTU auto tunning")
