RFR: 8364184: [REDO] AArch64: [VectorAPI] sve vector math operations are not supported after JDK-8353217

[Fei Gao]

This patch fixes a typo introduced in JDK-8353217, which incorrectly disabled SVE vector math symbols. As a result, some vector math test cases such as `jdk/incubator/vector/Double256VectorTests.java` threw
exceptions on 256-bit `sve` machines with errors like:
`java.lang.InternalError: not supported: ACOS Species[double, 4, S_256_BIT] acosdx_u10sve.`

`test/jdk/jdk/incubator/vector` passed on 256-bit `sve` and `neon` machine.
