Maor Gottlieb c956940a4a RDMA/umem: Use dma-buf locked API to solve deadlock
The cited commit moves umem to call the unlocked versions of dmabuf
unmap/map attachment, but the lock is held while calling to these
functions, hence move back to the locked versions of these APIs.

Fixes: 21c9c5c0784f ("RDMA/umem: Prepare to dynamic dma-buf locking specification")
