Subject: [PATCH v4 9/9] syscalls/fanotify22: Test capture of multiple errors

When multiple FS errors occur, only the first is stored.  This testcase
validates this behavior by issuing two different errors and making sure
only the first is stored, while the second is simply accumulated in
error_count.
