Subject: [PATCH 4.19 35/57] bnxt_en: Release PCI regions when DMA mask setup fails during probe.

From: Michael Chan <michael.chan@...adcom.com>

[ Upstream commit c54bc3ced5106663c2f2b44071800621f505b00e ]

Jump to init_err_release to cleanup.  bnxt_unmap_bars() will also be
called but it will do nothing if the BARs are not mapped yet.

Fixes: c0c050c58d84 ("bnxt_en: New Broadcom ethernet driver.")
