i386/testsuite: Correct AVX10.2 FP8 test mask usage

Under FP8, we should not use AVX512F_LEN_HALF to get the mask size since
it will get 16 instead of 8 and drop into wrong if condition. Correct
the usage for vcvtneph2[b,h]f8[,s] runtime test.

gcc/testsuite/ChangeLog:

	* gcc.target/i386/avx10_2-512-vcvtneph2bf8-2.c: Correct 128bit
	mask usage.
	* gcc.target/i386/avx10_2-512-vcvtneph2bf8s-2.c: Ditto.
	* gcc.target/i386/avx10_2-512-vcvtneph2hf8-2.c: Ditto.
	* gcc.target/i386/avx10_2-512-vcvtneph2hf8s-2.c: Ditto.
