arch_init: Simplify code for load_xbzrle()
For xbzrle_decode_buffer(), when decoding contents will exceed writing buffer, it will return -1, so need not check the return value whether large than writing buffer. And when failure occurs within load_xbzrle(), it always return -1 without any resources which need release. So can remove the related checking statements, and also can remove 'rc' and 'ret' local variables, Signed-off-by: Chen Gang <gang.chen.5i5j@gmail.com> Signed-off-by: Juan Quintela <quintela@redhat.com>
