Fixup various errors detected by pylint

I've been running pylint on a subset of anaconda:
booty storage iw/*.py platform.py

And it has found various errors this commit fixes:
- Restore line accidently dropped from iscsi.py
- execWithPulseProgress should propagate the return value of
  execWithCallback
- storage.formats.fs:535 (FS.doCheck): self.intf should be just intf
- storage.formats.fs: add missing "import sys" (for sys.exit)
- advanced_config.py add missing import for NetworkConfigurator
- lvm_dialog_gui.py: VolumeGroupEditor.editLogicalVolume dev was renamed to d
- partition_gui.py: remove an unneeded semicolon
- partition_gui.py: PartitionWindow.createCB rc should be dialog_rc
- storage.FSSet.write: put docstring in the proper place
- platform.Sparc.minimumSector: sectors should be sector
