i965/vec4: pass the correct src_sz to emit_send at emit_untyped_atomic
If the src is invalid, so src size is zero, the src_sz passed to emit send should be zero too, instead of a default 1 if we are in a simd4x2 case. This can happens if using emit_untyped_atomic for an atomic dec/inc. v2: use the proper src_sz when calling emit_send, instead of just avoid loading src at emit_send if BAD_FILE (Francisco Jerez) Reviewed-by: Francisco Jerez <currojerez@riseup.net>
