amr: use sizeof(struct amr_hdr) when working with amr header length

The header of an AMR header payload is 2 bytes long. At the moment we
use just a constant of 2 when we refer to the header length, but we have a
struct amr_hdr defined. Lets use sizeof(struct amr_hdr) to make it more
clear that we are refering to the header length.
