floppy: fix another use-after-free
While scanning the floopy code due to c093ee4f07f4 ("floppy: fix
use-after-free in module load failure path"), I found one more instance
of trying to access disk->queue pointer after doing put_disk() on
gendisk. For some reason , floppy moule still loads/unloads fine. The
object is probably still around with right pointer values.
o There seems to be one more instance of trying to cleanup the request
queue after we have called put_disk() on associated gendisk.
o This fix is more out of code inspection. Even without this fix for
some reason I am able to load/unload floppy module without any
issues.
o Floppy module loads/unloads fine after the fix.
