arm: virt: Fix segmentation fault when specifying an unsupported CPU
Using -cpu cortex-a9 (or any other unsupported CPU) with the virt board will cause QEMU to segmentation fault. This bug was introduced in commit 9ac4ef77, which incorrectly added a NULL terminator when converting the VirtBoardInfo array into a simple array of strings defining the valid CPUs. The cpuname_valid() loop already has a termination condition based on ARRAY_SIZE, so the NULL is spurious and causes the strcmp() to segfault if we reach it. Delete the NULL.
