s390/sclp: Add timeout to Store Data requests
Due to a bug in some firmware versions, Store Data requests might not
get an event response in certain situations. As a result, the boot
process will be blocked indefinitely.
Fix this by introducing timeout handling for Store Data requests. In
case a timeout occurs, the Store Data operation is halted and no data
is retrieved from the SCLP facility.
Note: A minority of installed systems rely on Store Data result for
device auto-configuration. These systems will fail to boot in case of a
Store Data timeout and will need to be switched to manual device
configuration as workaround.
