asix-sigma: fix incorrect pointer cast (non-aligned memory and endiannes issue)

This fixes the following warning:

asix-sigma.c: In function 'receive_data':
asix-sigma.c:1064:4: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
    devc->state.lastts = *(uint16_t *) buf - 1;
