* @brief Create a Lancer dump into a memory buffer
* @par Description
* This function creates a DMA buffer to hold a Lancer dump,
* sets the dump location to point to that buffer, then calls
* ocs_gen_dump to cause a dump to be transfered to the buffer.
* After the dump is complete it copies the dump to the provided
* user space buffer.
*
* @param ocs Pointer to ocs structure
* @param buf User space buffer in which to store the dump
* @param buflen Length of the user buffer in bytes
*
* @return Returns 0 on success, non-zero on error.
