6b661b7ed7 target/avr: Improve decode of LDS, STS 
The comment about not being able to define a field with
zero bits is out of date since 94597b6146
("decodetree: Allow !function with no input bits").

This fixes the missing load of imm in the disassembler.

Cc: qemu-stable@nongnu.org
Fixes: 9d8caa67a2 ("target/avr: Add support for disassembling via option '-d in_asm'")
