RDMA/bnxt_re: Fix incorrect BAR check in bnxt_qplib_map_creq_db()

Browse source

[ Upstream commit 145a417a39 ]

RCFW_COMM_CONS_PCI_BAR_REGION is defined as BAR 2, so checking
!creq_db->reg.bar_id is incorrect and always false.

pci_resource_start() returns the BAR base address, and a value of 0
indicates that the BAR is unassigned. Update the condition to test
bar_base == 0 instead.

This ensures the driver detects and logs an error for an unassigned
RCFW communication BAR.
