If allocating memory for the target SVE state in za_set() fails we clear TIF_SME for the ptracing task which is obviously not correct. If we are here we know that the target task already had neither TIF_SVE nor TIF_SME set since we only need to allocate if either the target had not used either SVE or SME and had no need to allocate state before or we just changed the vector length with vec_set_vector_length() which clears TIF_ for us on allocation failure so just remove the clear entirely.

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.
