bnxt_en: do not map packet buffers twice

Browse source

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.
