Bridge: Don't suspend/unspend the channel for interception routines.

By their nature, the connected line and redirecting interception routines
are not supposed to affect the channel's media.  Therefore, they should
not suspend and unsuspend the channel while running.  The
suspend/unsuspend operations could be expensive depending upon the bridge
and channel technology involved.
