    LINUX: Initialize CellLRU during osi_Init
    When OpenAFS kernel module gets loaded, it will create certain entries
    in "proc" filesystem. One of those entries is "CellServDB", in case
    we read "/proc/fs/openafs/CellServDB" without starting "afsd" it will
    result in crash with NULL pointer deref. The reason for crash is
    CellLRU has not been initialized yet (since "afsd" is not started)
    i.e afs_CellInit is not yet called, because of this "next" and "prev"
    pointers will be NULL. Inside "c_start()" we do not check for NULL
    pointer while traversing CellLRU and this causes crash.
    To avoid this initialize CellLRU during module intialization.
