[PATCH 07/10] x86emul: AVX512F scatter insns are memory writes

[Jan Beulich <jbeulich@xxxxxxxx>]

While the custom handling renders the "to_mem" field generally unused,
x86_insn_is_mem_write() still (indirectly) consumes that information,
and hence the table entries want to be correct.

Fixes:  ("x86emul: support AVX512F scatter insns")
