s390/bpf: clear correct BPF accumulator register
Currently we assumed the following BPF to eBPF register mapping:
- BPF_REG_A -> BPF_REG_7
- BPF_REG_X -> BPF_REG_8
Unfortunately this mapping is wrong. The correct mapping is:
- BPF_REG_A -> BPF_REG_0
- BPF_REG_X -> BPF_REG_7
So clear the correct registers and use the BPF_REG_A and BPF_REG_X
macros instead of BPF_REG_0/7.
