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.
