syncop: remove unnecessary call to gf_backtrace_save()
A call to gf_backtrace_save() was done on each context switch of a
synctask. The backtrace is generated writing to the filesystem, so it
can have an important impact on latency.
The generated backtrace was not used anywhere, so it's been removed.
