[PATCH 2/5] qemuDomainBlockPivot: Move check prior to executing the pivot steps

[Peter Krempa <pkrempa@xxxxxxxxxx>]

Move the check whether the job is already synchronised to the beginning
of the function so that we don't try to do some of the steps necessary
for pivoting prior to actually wanting to pivot.
