bnxt_en: Fix RSS context delete logic

In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Fix RSS context delete logic We need to free the corresponding RSS context VNIC in FW everytime an RSS context is deleted in driver. Commit 667ac333dbb7 added a check to delete the VNIC in FW only when netif_running() is true to help delete RSS contexts with interface down. Having that condition will make the driver leak VNICs in FW whenever close() happens with active RSS contexts. On the subsequent open(), as part of RSS context restoration, we will end up trying to create extra VNICs for which we did not make any reservation. FW can fail this request, thereby making us lose active RSS contexts. Suppose an RSS context is deleted already and we try to process a delete request again, then the HWRM functions will check for validity of the request and they simply return if the resource is already freed. So, even for delete-when-down cases, netif_running() check is not necessary. Remove the netif_running() condition check when deleting an RSS context.

Linux kernel 安全漏洞

Linux kernel是美国等都是美国(Linux)基金会的产品。Linux kernel是开源操作系统Linux所使用的内核。roc req等都是(roc)个人开发者的产品。req是一个使用 Black Magic 的简单 Go HTTP 客户端。ClickHouse ch等都是(ClickHouse)开源的产品。ch是一个ClickHouse的低级Go客户端。 Linux kernel存在安全漏洞，该漏洞源于bnxt_en驱动在RSS上下文删除逻辑中未正确释放VNIC，可能导致VNIC泄漏和后续请求
