      LE Remove Isochronous Data Path (0x08|0x006f) ncmd 1
        Status: Command Disallowed (0x0c)
        Connection handle: 96

It could happen after switching from Music -> Phonecall -> Music -> Phonecall.
Android incorrectly tries to clear two directions but only one was set.
This could result in no properly released stream.

Also this patch handle Command Disallowed for the data path operation.
Since Data Path is removed on CIS disconnection, Android ignores the
error code and continues with dropping stream.
