If bnxt_pci_mapping() succeeds in mapping BAR0 but fails while mapping BAR2, bnxt_attach_pre() previously skipped bnxt_pci_mapping_free() and only disabled bus mastering. Route the failure path through free_pci_map so any partially mapped PCI BAR resources are released. Remove the now-unused pci_map_fail label. Signed-off-by: Haoxiang Li <lihaoxiang@isrc.iscas.ac.cn>
