Diff v2 vs v1:
1. Remove set scsi host state by sysfs, as set host state by sysfs
may lead to functional issue. Scsi host state has it's own running
state machine.
2. Introduce 'blocked' sysfs api for set scsi host blocking IO. Use
this function we can do some test.

Ye Bin (3):
scsi: forbid to set scsi host state by sysfs
scsi: introduce 'blocked' sysfs api
scsi: blocking IO when host is set blocked
