Subject: [PATCH] floppy: remove redundant assignment to variable st

From: Colin Ian King <colin.king@canonical.com>

The variable st is being assigned a value that is never read and
it is being updated later with a new value. The initialization is
redundant and can be removed.

Addresses-Coverity: ("Unused value")
