protocol/gsm_04_08.h: drop incorrect GSM48_PDISC_USSD

According to the GSM TS 04.07, section 11.2.3.1.1 "Protocol
discriminator", bits 1 to 4 of the first octet of a standard
L3 message contain the protocol discriminator IE.

Meanwhile, the GSM48_PDISC_USSD represents value 0x11, i.e.
0b10001, that requires 5 bits, and moreover it is not
documented anywhere. Let's drop it.
