dm crypt: rename struct convert_context sector field
Rename sector to cc_sector in dm-crypt's convert_context struct. This is preparation for a future patch that merges dm_io and convert_context which both have a "sector" field. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
