Update path_offline() to return device status
A SCSI device can have for more states than just 'offline' and
'running'. In fact, any device _not_ in state 'running' is
unaccessible to I/O, so running a path checker on these devices
will cause the checker to be delayed and hence stall the entire
daemon.
This patch updates the path_offline() function to return the
actual device state. Path checkers will only be run if the
state is PATH_UP. A 'blocked' device state will be translated
into PATH_PENDING, causing the checkerloop to skip this device
and recheck as soon as possible.
