    Linux: afs_fill_super: Call bdi_destroy on the failure path
    
    Without this, if AFS startup failed, then trying to start AFS again
    triggers these warnings:
    
    WARNING: CPU: 3 PID: 657 at /build/buildd/linux-3.12.0/fs/sysfs/dir.c:526 sysfs_add_one+0xa5/0xd0()
    sysfs: cannot create duplicate filename '/devices/virtual/bdi/afs'
    
    WARNING: CPU: 3 PID: 657 at /build/buildd/linux-3.12.0/lib/kobject.c:196 kobject_add_internal+0x1f4/0x300()
    kobject_add_internal failed for afs with -EEXIST, don't try to register things with the same name in the same directory.
    
    and leads to general system instability.  This can be reproduced by
    starting AFS twice with an empty cache, dynroot disabled, and no
    network.
