Remove Coverity Scan CID 261519 (Using uninitialized value tmp. Field tmp.elems is uninitialized when calling _mm256_insert_epi16.)

Remove Coverity Scan CID 261470 (Using uninitialized value tmp. Field tmp.elems is uninitialized when calling _mm256_insert_epi8.)

Remove Coverity Scan CID 60471 (Function memory_read does not terminate string *user->nas_user_nvdata.)

Remove Coverity Scan CID 60241 (Passing &eplmn to function emm_proc_attach_accept which uses it as an array. This might corrupt or misinterpret adjacent memory locations.)

If several UEs are removed, the variable ue_to_be_removed may be overwritten.
Let's use an array instead.

Fix Coverity Scan CID 339954 (Overrunning callee's array of size 16 by passing argument ue_id (which evaluates to 65535) in call to flexran_set_ue_ul_slice_idx.)

Fix Coverity Scan CID 339964 (Passing &rrc_eNB_mui to function rrc_eNB_process_S1AP_DOWNLINK_NAS which uses it as an array. This might corrupt or misinterpret adjacent memory locations.)

Fix Coverity Scan CID 339974 (Overrunning array eutra_bandtable of 48 24-byte elements at element index 48 (byte offset 1152) using index i (which evaluates to 48).)

Fix Coverity Scan CID 340209 (Variable message_p going out of scope leaks the storage it points to.)

Fix Coverity Scan CID 340211 (Variable message_p going out of scope leaks the storage it points to.)

Fix Coverity Scan CID 340232 (Variable message_p going out of scope leaks the storage it points to.)

Fix Coverity Scan CID 340235 (Using variable UE_id_mac as an index to array RC.mac[ctxt_pP->module_id]->UE_list.UE_sched_ctrl.)

Fix Coverity Scan CID 340243 (Overrunning array of 1 bytes at byte offset 1 by dereferencing pointer ie->value.choice.UESecurityCapabilities.encryptionAlgorithms.buf + 1.)
