octeontx2-pf: Fix devm_kcalloc() error checking

[ Upstream commit 2e25935ed24daee37c4c2e8e29e478ce6e1f72c7 ]

The devm_kcalloc() function never return error pointers, it returns NULL
on failure.  Also delete the netdev_err() printk.  These allocation
functions already have debug output built-in some the extra error message
is not required.
