[ Upstream commit 23c93c3b6275a59f2a685f4a693944b53c31df4e ]
Remove double-mapping of DMA buffers as it can prevent page pool entries
from being freed. Mapping is managed by page pool infrastructure and
was previously managed by the driver in __bnxt_alloc_rx_page before
allowing the page pool infrastructure to manage it.
Fixes: 578fcfd26e2a ("bnxt_en: Let the page pool manage the DMA mapping")
