[PATCH net] net: mvneta_bm: fix gen_pool_free address for BPPI

[Chenguang Zhao <chenguang.zhao@linux.dev>]

From: Chenguang Zhao <zhaochenguang@kylinos.cn>

gen_pool_free() expects the virtual address returned by
gen_pool_dma_alloc(), not the physical address. Passing phys can miss
the chunk and trigger BUG() on remove or probe rollback.

Fixes: dc35a10f68d3 ("net: mvneta: bm: add support for hardware buffer management")
