net: dpaa_eth: extract hash using __be32 pointer in rx_default_dqrr()

Sparse provides the following output:

warning: cast to restricted __be32

This is a harmless warning due to the fact that we dereference the hash
stored in the FD using an incorrect type annotation. Suppress the
warning by using the correct __be32 type instead of u32. No functional
change.
