lib/accel: API to get memory domains per opcode 



There is an accel module API to return a memory domain
but no public wrapper for it. Next patch uses
the new API in vbdev_crypto

 * \param array_size size of \b domains array

 * \return the number of entries in \b domains array or negated errno. If returned value is bigger than \b array_size passed by the user

  * then the user should increase the size of \b domains array and call this function again. There is no guarantees that

  * the content of \b domains array is valid in that case.
