[PATCH net v3 0/2] net/stmmac: Secure against failures of DMA memory allocation

[Jakub Raczynski]

This series fixing two issues related to fails of
__alloc_dma_rx_desc_resources(). Original issue from 1st patch is related to
page_pool that has happened in testing env, while second was requested by
Sashiko to have similar change for DMA allocation. 
To have complete fix for all failures of __alloc_dma_rx_desc_resources(),
merge two fixes into series.

---
Changes in v3:
- Added null assignment to page pointers (suggested by sashiko)
- Convert IS_ERR_OR_NULL check to just NULL check

Changes in v2:
- Added reviewed by Maxime to first patch
- Dropped null check as page_pool_destroy() does provide that
- Modified comment to reflect that
