The 'pending' state needs to be handled by the blockjob code only when
the snapshot code requests a block-commit without auto-finalization.
If we always handle it we fail to properly remove the blockjob data for
the 'blockdev-create' job as that also transitions trhough 'pending' but
we'd never update it once it reaches 'concluded' as the code already
thinks that the job has finished and is no longer watching it.
Introduce a 'processPending' property into block job data and set it
only when we know that we need to process 'pending'.
