tsnep: Fix tsnep_tx_unmap() error path usage

Browse source

commit b3bb8628bf upstream.

If tsnep_tx_map() fails, then tsnep_tx_unmap() shall start at the write
index like tsnep_tx_map(). This is different to the normal operation.
Thus, add an additional parameter to tsnep_tx_unmap() to enable start at
different positions for successful TX and failed TX.
