kselftest/arm64: Fix test for streaming FPSIMD write in sve-ptrace
Since f916dd32a943 ("arm64/fpsimd: ptrace: Mandate SVE payload for
streaming-mode state") we do not support writing FPSIMD payload data when
writing NT_ARM_SSVE but the sve-ptrace test has an explicit test for
this being supported which was not updated to reflect the new behaviour.
Fix the test to expect a failure when writing FPSIMD data to the
streaming mode register set.
