sdk: packDev_t: Properly and entirely fill entire struct

The values from associated_devices_t struct after linkInfo.txFailure were
not written to the buffer at all (without the proper pointer increment, they
would have been written to the wrong spot anyway). So this part of the buffer
also contained uninitialized memory only. I completed the function to copy
the entire struct, because the endDev.deviceTimeout and timeoutCounter were
particularly interesting for me to inspect child aging.
