net/mlx5: Avoid passing dma address 0 to firmware
commit 6b276190c50a12511d889d9079ffb901ff94a822 upstream.
Currently the firmware can't work with a page with dma address 0.
Passing such an address to the firmware will cause the give_pages
command to fail.
To avoid this, in case we get a 0 dma address of a page from the
dma engine, we avoid passing it to FW by remapping to get an address
other than 0.
Fixes: bf0bf77f6519 ('mlx5: Support communicating arbitrary host...')
