floppy: cleanup: remove redundant assignment to nr_sectors
Variable nr_sectors is set to zero but this value is never read as it is overwritten later on, hence it is a redundant assignment and can be removed. Clean up the following clang-analyzer warning: drivers/block/floppy.c:2333:2: warning: Value stored to 'nr_sectors' is never read [clang-analyzer-deadcode.DeadStores].
