    LINUX: Avoid premature RO volume lock error
    
    Commit 0fc27471e7da0c5de4addcdec1bfbca5208072cc avoids processing lock
    requests for RO volumes, but it did this both in afs_lockctl() and in
    the Linux-specific afs_linux_lock(). The changes in afs_linux_lock()
    are incorrect, since they also avoid F_GETLK requests (whereas
    afs_lockctl() just avoids F_SETLK* requests).
    
    Additionally, the section in afs_linux_lock() incorrectly reports an
    error, since it returns a positive EBADF error code, when we are
    supposed to return -EBADF.
    
    The result of all of this is that an F_GETLK F_WRLCK request for an RO
    volume always fails with fcntl() returning 9 (EBADF), which is an
    invalid return code for fcntl() F_GETLK (instead we should return -1
    with an errno of 9). But if there are no locks, we should return
    success anyway.
    
    Just remove this section, since afs_lockctl() handles this case itself
    anyway.
    
    Thanks to Todd Lewis for reporting this issue.
