eth: mlx4: Fix IS_ERR() vs NULL check bug in mlx4_en_create_rx_ring
[ Upstream commit e580beaf43d563aaf457f1c7f934002355ebfe7b ]
Replace NULL check with IS_ERR() check after calling page_pool_create()
since this function returns error pointers (ERR_PTR).
Using NULL check could lead to invalid pointer dereference.
