l1sap: fix rach reason (ra) parsing
The ra parameter indicates the reason for the received rach request. osmo-bts uses the ra parameter to determine if the received rach request is packet access related. If yes, osmo-bts will forward the request to the PCU. In order to determine if the ra is packet related or not, the higher 4 bits must be equel to 0x7 and at least one of the lower 4 bits must be zero. The current method lacks checking of the lower 4 bits. It would also accept 0b01111111, which is reserved for future use. This commit extends the check to take also the last 4 bits into accound.
