[PATCH 1/3] android/socket: Refactor connect to allow directly connect to rfcomm

[Andrei Emeltchenko <Andrei.Emeltchenko.news@gmail.com>]

From: Andrei Emeltchenko <andrei.emeltchenko@intel.com>

Since Socket HAL allows us to specify RFCOMM channel number and directly
connect refactor send function to allow connect directly is uuid is zero
and channel number is specified.
