Subject: [PATCH] net/mvpp2: check pointer before using it

[ upstream commit 42ab8427d4c67532df0b91b8e55e695f8c4f3bb6 ]

Avoid NULL dereference by checking pointer before using it.

Note that the fixes tag is before the driver was renamed
to mvpp2, so the patch will not apply that far back.

Fixes: 3588aaa68eab ("net/mrvl: fix HIF objects allocation")
