Error responses from swtpm are typically only 4 bytes long with the exception of a few commands that return more bytes. Therefore, read the entire response in 2 steps and stop if the first few bytes indicate an error response with no subsequent bytes readable. Read the rest in a 2nd step, if needed. This avoids getting stuck while waiting for too many bytes in case of an error. The 'getting stuck' condition has not been observed in practice so far, though.
