staging: unisys: visorbus: visorchipset.c: Fix bug in parser_init_byte_stream.

This patch fixes a bug in the function parser_init_byte_stream()
by removing the call to parser_done from goto err_finish_ctx.
The function parser_done() decrements
chipset_dev->controlvm_payload_bytes_buffered which is not
incremented before this gets called.
