Fix a deadlock in d-channel handling in chan_zap.

This deadlock was introduced by the fix to ensure that channels are properly
locked when handling channel variables.  There were sections of this code where
the channel pvt was locked before the channel lock, when in fact it _must_ be
the other way around.

(closes issue #11582)
