[SCSI] Allow error handling timeout to be specified
Introduce eh_timeout which can be used for error handling purposes. This was previously hardcoded to 10 seconds in the SCSI error handling code. However, for some fast-fail scenarios it is necessary to be able to tune this as it can take several iterations (bus device, target, bus, controller) before we give up. Signed-off-by: Martin K.
