    Fix deadlock from not releasing SS7 linkset lock.

    sig_ss7_hangup() failed to release the SS7 linkset lock if the call had
    the alreadyhungup flag set.

    * Made unlock the SS7 linkset lock in sig_ss7_hangup() if the
    alreadyhungup flag is set.

    * Made ss7_start_call() not hold any locks while creating the channel for
    an incoming call to prevent deadlock.

    * Made ss7_grab() a void function, since it could never fail, to simplify
    calling code.

    * Made obtain the channel lock to do softhangup in some places.
