Alexander Usyskin 6b0b80ac10 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: 369aea8459 ("mei: implement client dma setup.")
