Subject: Fix: directory-handle: use of free'd handle on fstat() error
X-Git-Tag: v2.13.0-rc1~749

Fix: directory-handle: use of free'd handle on fstat() error

On an error to fstat a directory handle, a directory handle is
released and is still initialized as if the error had not occurred.

Return NULL early from lttng_directory_handle_create_from_dirfd()
to prevent those erroneous accesses.
