Title
net/mlx5e: xsk: Fix DMA and xdp_frame leak on XDP_TX xmit failure
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/mlx5e: xsk: Fix DMA and xdp_frame leak on XDP_TX xmit failure
In the XSK branch of mlx5e_xmit_xdp_buff(), when sq->xmit_xdp_frame()
returns false (e.g. XDPSQ is full), the function returns without
unmapping the DMA address or freeing the xdp_frame allocated by
xdp_convert_zc_to_xdp_frame(). The xdpi_fifo push only happens on
success, so the completion path cannot recover these entries.
With CONFIG_DMA_API_DEBUG=y, the leak surfaces on driver unbind:
DMA-API: pci 0000:08:00.0: device driver has pending DMA
allocations while released from device [count=1116]
One of leaked entries details: [device address=0x000000010ffd7028]
[size=1534 bytes] [mapped with DMA_TO_DEVICE] [mapped as phy]
WARNING: kernel/dma/debug.c:881 at dma_debug_device_change+0x127/0x180
...
DMA-API: Mapped at:
debug_dma_map_phys+0x4b/0xd0

mlx5e_handle_rx_cqe_mpwrq+0xc1/0x290 [mlx5_core]
Add the missing unmap + xdp_return_frame, matching the cleanup already
done in mlx5e_xdp_xmit(). has_frags is rejected earlier in this branch,
so no per-frag unmap is needed.
