Alexei Starovoitov 265d7657c9 bpf: fix 32-bit divide by zero ...

[ upstream commit 68fda450a7 ]

due to some JITs doing if (src_reg == 0) check in 64-bit mode
for div/mod operations mask upper 32-bits of src register
before doing the check

Fixes: 622582786c ("net: filter: x86: internal BPF JIT")
Fixes: 7a12b5031c ("sparc64: Add eBPF JIT.")
