scsi: target: configfs: Delete unnecessary checks for NULL

Browse Source 
The "item" pointer is always going to be valid pointer and does not need to
be checked.

But if "item" were NULL then item_to_lun() would not return a NULL, but
instead, the container_of() pointer math would return a value in the error
pointer range.  This confuses static checkers since it looks like a NULL vs
IS_ERR() bug.

Delete the bogus checks.
