Jacob Keller 69077577af i40e: avoid permanent lock of *_PTP_TX_IN_PROGRESS ... The i40e driver uses a bit lock to indicate when a Tx timestamp is in progress to avoid attempting to timestamp multiple packets at once. This is required because hardware only has registers to handle one request at a time. There is a corner case where we failed to cleanup the bit lock after a failed transmit. This can potentially result in a state bit being locked forever. Add some cleanup code to i40e_xmit_frame_ring to check and make sure we cleanup incase of these failures. We also modify i40e_tx_map to return an error code indication DMA failure.
