loop: Properly clear sysfs in autoclear mode
In autoclear mode bdev is NULL but the sysfs
entry should be destroyed otherwise this warning appears:
WARNING: at fs/sysfs/dir.c:451 sysfs_add_one+0x82/0x95()
sysfs: cannot create duplicate filename '/devices/virtual/block/loop0/loop'
Fixes commit ee86273062cbb310665fe49e1f1937d2cf85b0b9
