emit_ldx_r() and emit_a32_mov_i() were both using TMP_REG_1 and
clashing with each other. Using TMP_REG_2 in emit_ldx_r() fixes
the issue.

[ Note, this has been implicitly fixed upstream by a6eccac507e
("ARM: net: bpf: 64-bit accessor functions for BPF registers"),
so the fix here is a minimal stand-alone fix for 4.14. test_bpf
suite runs without error after the fix. ]
Queued for 4.14, thank you.
