#     afs: Fix unpinned address list during probing
#     
#     When it's probing all of a fileserver's interfaces to find which one is
#     best to use, afs_do_probe_fileserver() takes a lock on the server record
#     and notes the pointer to the address list.
#     
#     It doesn't, however, pin the address list, so as soon as it drops the
#     lock, there's nothing to stop the address list from being freed under
#     us.
#     
#     Fix this by taking a ref on the address list inside the locked section
#     and dropping it at the end of the function.
#     
#     Fixes: 3bf0fb6f33dd ("afs: Probe multiple fileservers simultaneously")
