Michal Kalderon a25984f3ba RDMA/qedr: Fix null-pointer dereference when calling rdma_user_mmap_get_offset ... When running against rdma-core that doesn't support doorbell recovery, the rdma_user_mmap_entry won't be allocated for doorbell recovery related mappings. We have a flag indicating whether rdma-core supports doorbell recovery or not which was used during initialization, however some cases didn't check that the rdma_user_mmap_entry exists before attempting to acquire it's offset.
