habanalabs: patched cb equals user cb in device memset

[ Upstream commit cf01514c5c6efa2d521d35e68dff2e0674d08e91 ]

During device memory memset, the driver allocates and use a CB (command
buffer). To reuse existing code, it keeps a pointer to the CB in two
variables, user_cb and patched_cb. Therefore, there is no need to "put"
both the user_cb and patched_cb, as it will cause an underflow of the
refcnt of the CB.
