[ Upstream commit 38b2db564d9ab7797192ef15d7aade30633ceeae ]
The be_fill_queue() function can only fail when "eq_vaddress" is NULL and since it's non-NULL here that means the function call can't fail. But imagine if it could, then in that situation we would want to store the "paddr" so that dma memory can be released.
