Supreeth Herle 6ffdce598a Fix attach reject when ULA subscription data does not contain MSISDN (#1524)
Issue:
When the ULA - Subscription Data does not contain MSISDN, the Create Session Request
from MME to SGW does not contain MSISDN IE resulting in SMF throwing following log

smf        | 05/09 15:20:53.683: [smf] ERROR: No MSISDN (../src/smf/s5c-handler.c:82)
sgwc       | 05/09 15:20:53.683: [sgwc] ERROR: No Context in TEID (../src/sgwc/s5c-handler.c:104)
mme        | 05/09 15:20:53.683: [mme] ERROR: No Context in TEID (../src/mme/mme-s11-handler.c:122)

As per 3GPP TS 29.274 version 16.5.0, table 7.2.1-1: MSISDN IE shall only be included
in Create Session Request if its provided in subscription data from the HSS. This commit
fixes this by removing the mandatory MSISDN IE check in SMF.
