Updated patch to address comments from Andreas Herrman, who noted that
the initialization, with the HZ, was inconsistent with its use in the
FC transport.

This patch ups the maximum limit for how long an sdev is allowed to
be blocked. Originally, the value was 60 seconds. However, we are aware
of array failover and switch reboot times that can be as high
as 90 seconds. We're proposing to change the max to 120 seconds.
