Kirill A. Shutemov 85fd85bc02 x86/insn: Fix CTEST instruction decoding
insn_decoder_test found a problem with decoding APX CTEST instructions:

	Found an x86 instruction decoder bug, please report this.
	ffffffff810021df	62 54 94 05 85 ff    	ctestneq
	objdump says 6 bytes, but insn_get_length() says 5

It happens because x86-opcode-map.txt doesn't specify arguments for the
instruction and the decoder doesn't expect to see ModRM byte.

Fixes: 690ca3a306 ("x86/insn: Add support for APX EVEX instructions to the opcode map")
