ran_msg_iu: do not pass UEA0 to ranap_new_msg_sec_mod_cmd2()

On the protocol level, it's impossible to indicate UEA0 together
with the other algorithms.  The encryption is either a) disabled,
so the Encryption Information IE is not present, or b) enabled,
so the Encryption Information IE indicates UEA1 and/or UEA2.

Because of that, the ranap_new_msg_sec_mod_cmd2() would fail to
generate the RANAP PDU if the given bitmask has the UEA0 bit set.

Fixes: 505a94a610fc ("Make UTRAN encryption algorithms configurable")
