[ Upstream commit 6f0315330af7a57c1c00587fdfb69c7778bf1c50 ]
The test case for SME vector length changes via sigreturn use a bit too
much cut'n'paste and only actually changed the SVE vector length in the
test itself. Andre's recent factoring out of the initialisation code caused
this to be exposed and the test to start failing. Fix the test to actually
cover the thing it's supposed to test.

KSelfTest ARM64
===============
- These tests are arm64 specific and so not built or run but just skipped
completely when env-variable ARCH is found to be different than 'arm64'
and `uname -m` reports other than 'aarch64'.
- Holding true the above, ARM64 KSFT tests can be run within the KSelfTest
framework using standard Linux top-level-makefile targets:
$ make TARGETS=arm64 kselftest-clean
$ make TARGETS=arm64 kselftest
or
$ make -C tools/testing/selftests TARGETS=arm64 \
INSTALL_PATH=<your-installation-path> install
or, alternatively, only specific arm64/ subtargets can be picked:
$ make -C tools/testing/selftests TARGETS=arm64 ARM64_SUBTARGETS="tags signal" \
INSTALL_PATH=<your-installation-path> install
Further details on building and running KFST can be found in:
