[S390] qdio: fix qdio_activate timeout handling.
Current code in qdio_activate waits for at least 5 seconds
until it returns. It may return earlier if an error occurs,
but not if everything is ok. This large timeout value
became visible with commit dfa77f611ff295598e218aa0eb6efa73a5cf26d0
"qdio: set QDIO_ACTIVATE_TIMEOUT to 5s", which intended to
fix the timeout value which was zero. In turn setting an
FCP adapter online took 5 seconds.
In practice waiting for 5ms before continuing is sufficient
as pointed out by Utz Bacher and Cornelia Huck.
