Subject: [PATCH net-next] net: ethernet: ti: fix return value check in k3_cppi_desc_pool_create_name()

In case of error, the function gen_pool_create() returns NULL pointer
not ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.

Fixes: 93a76530316a ("net: ethernet: ti: introduce am65x/j721e gigabit eth subsystem driver")
