[NGAP] Fix incorrect AMF Set ID type (uint8 → uint16) causing AMF lookup failure
This PR fixes issue #1012 , a data type issue related to the AMF Set ID used
during UE RRC reestablishment. The AMF Set ID was mistakenly declared as uint8_t
instead of uint16_t, even though it is a 10-bit field as specified in 3GPP TS
23.003 section 2.10.1. As a result, AMF Set IDs greater than 255 were truncated,
leading to failed AMF lookups and the following warning: No matching AMF found
for PLMN (MCC=%03d MNC=%0*d) and AMF SetID=%u.
Verified reestablishment succeeds with AMF Set IDs >255.
