[SCSI] zfcp: Simplify and update ct/gs and els timeout handling

The recommendation for a timeout of 2 * R_A_TOV is the same for ct/gs
and els requests, so set it in the common function used for
initializing both request types. Besides, the timer inside zfcp should
only run longer than the timeout set for the channel, so 10 seconds
more should be enough (instead of 60 seconds).
