arm64: bpf: fix endianness conversion bugs
Upper bits should be zeroed in endianness conversion:
- even when there's no need to change endianness (i.e., BPF_FROM_BE
on big endian or BPF_FROM_LE on little endian);
- after rev16.
This patch fixes such bugs by emitting extra instructions to clear
upper bits.
