RDMA/bnxt_re: Avoid exposing umdbr to userspace

Browse source

The umdbr field in struct bnxt_re_db_region returns the raw
unmapped PCI BAR address of the doorbell region. Avoid sharing
this field to the userspace. Change this to a reserved field
and stop populating it, keeping the ABI layout and size
unchanged for existing binaries.
