riscv: Fix check_unaligned_access_all_cpus
check_vector_unaligned_access_emulated_all_cpus(), like its name suggests, will return true when all cpus emulate unaligned vector accesses. If the function returned false it may have been because vector isn't supported at all (!has_vector()) or because at least one cpu doesn't emulate unaligned vector accesses. Since false may be returned for two cases, checking for it isn't sufficient when attempting to determine if we should proceed with the vector speed check. Move the !has_vector() functionality to check_unaligned_access_all_cpus() in order for check_vector_unaligned_access_emulated_all_cpus() to return false for a single case.
