Zheng Yongjun 0906f3a3df net: sparx5: switchdev: fix possible NULL pointer dereference 
As the possible failure of the allocation, devm_kzalloc() may return NULL
pointer.
Therefore, it should be better to check the 'db' in order to prevent
the dereference of NULL pointer.

Fixes: 10615907e9b51 ("net: sparx5: switchdev: adding frame DMA functionality")
