crypto: qat - handle retries due to collisions in adf_iov_putmsg()

Browse source

Rework __adf_iov_putmsg() to handle retries due to collisions
internally, removing the need for an external retry loop.
The functions __adf_iov_putmsg() and adf_iov_putmsg() have been merged
together maintaining the adf_iov_putmsg() name.

This will allow to use this function only for GEN2 devices, since
collision are peculiar of this generation and therefore should be
confined to the actual implementation of the transport/medium access.

Note that now adf_iov_putmsg() will retry to send a message only in case
of collisions and will now fail if an ACK is not received from the
remote function.
