Subject: octeontx2-pf: Add check for devm_kcalloc
Patch-mainline: v6.1-rc7
Git-commit: cd07eadd5147ffdae11b6fd28b77a3872f2a2484
References: git-fixes
As the devm_kcalloc may return NULL pointer,
it should be better to add check for the return
value, as same as the others.
Fixes: e8e095b3b370 ("octeontx2-af: cn10k: Bandwidth profiles config support")
