[PATCH 1/3] net: stmmac: Fix error handling path in 'alloc_dma_rx_desc_resources()'

[Christophe JAILLET]

If the first 'kmalloc_array' within the loop fails, we should free what
as already been allocated, as done in all other error handling path.

Fixes: 54139cf3bb33 ("net: stmmac: adding multiple buffers for rx")
