    Linux 4.5: get_link instead of follow_link+put_link
    
    In linux commit 6b255391, the follow_link inode operation was
    replaced by the get_link operation, which is basically the same
    but takes the inode and dentry separately, allowing for the
    possibility of staying in RCU mode.
    
    For now, only support this if page_get_link is available and we are
    using the USABLE_KERNEL_PAGE_SYMLINK_CACHE
    
    The previous test for USABLE_KERNEL_PAGE_SYMLINK_CACHE used a bogus,
    undefined configure variable (ac_cv_linux_kernel_page_follow_link).
    Remove it, as it was not needed
