Mike Christie 4cbec7e89a scsi: target: Fix unmap setup during configuration 
This issue was found and also debugged by Carl Lei <me@xecycle.info>.

If the device is not enabled, iblock/file will have not setup their
se_device to bdev/file mappings. If a user tries to config the unmap
settings at this time, we will then crash trying to access a NULL pointer
where the bdev/file should be.

This patch adds a check to make sure the device is configured before
we try to call the configure_unmap callout.

Fixes: 34bd1dcacf ("scsi: target: Detect UNMAP support post configuration")
