gsm_08_08: correct speech codec defaults

The speech codec defaults are not correct. The defaults recommended
in 3GPP TS 28.062, Table 7.11.3.1.3-2 are limited by 3GPP TS 48.008,
Section 3.2.2.103. Some defaults are actually reserved for future
use. Also the endianess of the 16 bit values is reversed.

- correct values so that they match the specification
- transmit bytes in the correct endianess
