block: introduce BLK_STS_OFFLINE
Currently, drivers reports BLK_STS_IOERR for devices that are not full online or being removed. This behavior could cause confusion for users, as they are not really I/O errors from the device. Solve this issue with a new state BLK_STS_OFFLINE, which reports "device offline error" in dmesg instead of "I/O error". EIO is intentionally kept to not change user visible return value.
