ceph: don't blindly unregister session that is in opening state
handle_cap_export() may add placeholder caps to session that is in opening state. These caps' session pointer become wild after session get unregistered. The fix is not to unregister session in opening state during mds failovers, just let client to reconnect later when mds is recovered.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
