Fix arm64 panic

[andig]

Users of evcc.io have just reported this panic on arm64:

panic: unaligned 64-bit atomic operation
goroutine 246 [running]:
internal/runtime/atomic.panicUnaligned()
        internal/runtime/atomic/unaligned.go:8 +0x24
internal/runtime/atomic.Load64(0x6521a1c)

According to https://pkg.go.dev/sync/atomic#pkg-note-BUG:

On ARM, 386, and 32-bit MIPS, it is the caller's responsibility to arrange for 64-bit alignment of 64-bit words accessed atomically. The first word in a variable or in an allocated struct, array, or slice can be relied upon to be 64-bit aligned.

Rearranging the order of the structure fixes this.
