Subject: [PATCH net-next 3/3] bnxt_en: fix pci cleanup in bnxt_init_one() failure path
From: Sathya Perla <sathya.perla@...adcom.com>
In the bnxt_init_one() failure path, bar1 and bar2 are not
being unmapped. This commit fixes this issue. Reorganize the
code so that bnxt_init_one()'s failure path and bnxt_remove_one()
can call the same function to do the PCI cleanup.
