[ft2900] fix lockup issue (#2505)
This fixes an issue where memories entered via the Chirp UI and uploaded
to the radio could sometimes cause lockups if the memory was later edited
in the radio to change its SQLTYPE.  The cause was uninitized flags
that could erroneously flag a tone or DCS code as being part of a split
tone.  Fix is to initialize the flags to zero -- there was already code
to set them to 1 when needed.
