iser-target: Fix identification of login rx descriptor type
commit b89a7c25462b164db280abc3b05d4d9d888d40e9 upstream.
Once connection request is accepted, one rx descriptor
is posted to receive login request. This descriptor has rx type,
but is outside the main pool of rx descriptors, and thus
was mistreated as tx type.
