gsm690: Fix amr speech bit length table
The table amr_len_by_ft represents the length of the raw AMR speech bits
in bytes. The table is based on the Table found in RFC 4867 §3.6, Table 1,
Column "Total speech bits". The number of bits is divided by 8 and then
rounded up to get the number of consumed octets.
An AMR SID frame (including STI and MI) takes up 39 bits, this will
result in 5 octets, not in 7. Lets correct this.
