vkd3d-shader/ir: Avoid memset() in vsir_instruction_init().

Browse Source 
Primarily to avoid -Warray-bounds warnings from newer gcc, specifically
for the first vsir_instruction_init() call in vsir_update_dcl_temps().
This seems to be a false positive created by the interaction between
vsir_program_iterator_insert_after() and vsir_program_iterator_next()
error handling; it may be possible to avoid that by rearranging things,
but it doesn't seem worth it.
