Add proper error handling for when an async create fails. The inode never existed, so any dirty caps or data are now toast. We already d_drop the dentry in that case, but the now-stale inode may still be around. We want to shut down access to these inodes, and ensure that they can't harbor any more dirty data, which can cause problems at umount time. When this occurs, flag such inodes as being SHUTDOWN, and trash any caps and cap flushes that may be in flight for them, and invalidate the pagecache for the inode. Add a new helper that can check whether an inode or an entire mount is now shut down, and call it instead of accessing the mount_state directly in places where we test that now.

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.
