[ Upstream commit85fe9f565d] Fix a bug where the driver's event subscription logic for SRQ-related events incorrectly sets obj_type for RMP objects. When subscribing to SRQ events, get_legacy_obj_type() did not handle the MLX5_CMD_OP_CREATE_RMP case, which caused obj_type to be 0 (default). This led to a mismatch between the obj_type used during subscription (0) and the value used during notification (1, taken from the event's type field). As a result, event mapping for SRQ objects could fail and event notification would not be delivered correctly. This fix adds handling for MLX5_CMD_OP_CREATE_RMP in get_legacy_obj_type, returning MLX5_EVENT_QUEUE_TYPE_RQ so obj_type is consistent between subscription and notification.
