Zdenek Kabelac 044abcf91b Use sysfs to set/get of read-ahead ...

If we know major:minor number of device (which is known after resume) we will
try to use  sysfs to set/get read ahead parameters of device.
This avoid potential problem of blocking commands like 'dmsetup info' awaiting
for device being usable for open/close - i.e. overfilled thin pool may block
such command.
