iser-target: Fix non negative ERR_PTR isert_device_get usage

Browse source

As reported by Dan, isert_create_device_ib_res() failure within
isert_device_get() can potentially return a postive value,
resulting in ERR_PTR() triggering a NULL pointer dereference.

Caught by the static checker:

     drivers/infiniband/ulp/isert/ib_isert.c:423 isert_device_get()
     error: passing non negative 1 to ERR_PTR
