mei: hbm: fix client dma reply status
Don't blindly copy status value received from the firmware
into internal client status field,
It may be positive and ERR_PTR(ret) will translate it
into an invalid address and the caller will crash.
Put the error code into the client status on failure.
Fixes: 369aea845951 ("mei: implement client dma setup.")
