vkd3d-shader/d3dbc: Adjust the token count for DEF and DEFI instructions in shader_sm1_skip_opcode().
This was broken by commit e390bc35; that commit fixed the source count for these instructions, but didn't adjust shader_sm1_skip_opcode(). Note that this only affects shader model 1; later versions have a token count embedded in the initial opcode token.
