Nicholas Bellinger bdfb333556 target: Fix divide by zero bug in fabric_max_sectors for unconfigured devices 
commit 7a3cf6ca1a upstream

This patch fixes a possible divide by zero bug when the fabric_max_sectors
device attribute is written and backend se_device failed to be successfully
configured -> enabled.

Go ahead and use block_size=512 within se_dev_set_fabric_max_sectors()
in the event of a target_configure_device() failure case, as no valid
dev->dev_attrib.block_size value will have been setup yet.
