Fix cache misalignment after network load operations

After any operation that downloads a file (e.g., pxe get, or dhcp), the buffer containing the downloaded data is flushed. This patch rounds up the flushed size to a cacheline boundary, preventing a cache misalignment message from u-boot.

Looks like you missed to update the commit log for v2 as you are no longer flushing the cache :-)

Also, in the Subject line it is always good practice to start with the subsystem name, so something like:
net: Remove flush_cache() operation
