Eric Biggers 98ac3be360 generic: test encryption key revocation during concurrent I/O

Add a test which revokes a keyring key while other processes are
performing I/O on an encrypted file that was "unlocked" using that key.
The crashes unpatched kernels with filesystem encryption enabled.

This bug was present in kernels v4.2 and later.  It has been fixed in
v4.11-rc4, v4.10.7, v4.9.20, and v4.4.59.
