vkd3d-shader/d3dbc: Adjust the token count for DEF and DEFI instructions in shader_sm1_skip_opcode().

Browse Source 
This was broken by commit e390bc35e2c9b0a2110370f916033eea2366317e; 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.
