    afs: Make afs_osi_Free(NULL) a no-op
    
    In userspace, we assume that free(NULL) does nothing, which makes
    certain cleanup code paths simpler. This may or may not be true for
    our free() abstractions that can run in the kernel (like afs_osi_Free,
    rxi_Free, etc), which is confusing. To make the higher-level free()
    abstractions more consistent, change afs_osi_Free to guarantee that
    passing a NULL pointer does nothing.
