sync: Dump fence information on timeout

sync: Dump fence information on timeout

Currently we print only the fence memory address if the fence
times out. This is not enough for debugging *why* the fence timed
out.

This patch modifies timeout routine so that we print the syncpoints
that relate to the current fence.
