    LINUX: Don't panic on some file open errors
    
    Commit 'LINUX: Return NULL for afs_linux_raw_open error' (f6af4a155)
    updated afs_linux_raw_open to return NULL on some errors, but still
    panics if obtaining the dentry fails.
    
    Commit 'afs: Verify osi_UFSOpen worked' (c6b61a451) updated callers of
    osi_UFSOpen to verify whether or not the open was successful.  This
    meant osi_UFSOpen (and routines it calls) could pass back an error
    indication rather than panic when an error is encountered.
    
    Update afs_linux_raw_open to return a failure instead of panic if unable
    to obtain a dentry.
    
    Update osi_UFSOpen to return a NULL instead of panic if unable to obtain
    memory or fails to open the file. All callers of osi_UFSOpen handle a
    fail return, though some will still issue a panic.
    
    Update afs_linux_readpage_fastpath and afs_linux_readpages to not panic
    if afs_linux_raw_open fails.  Instead of panic, return an error.
    
    For testing, an error can be forced by removing a file from the
    cache directory.
