commit 02b4d71948b3(octeontx2-af: Skip PFs if not enabled) conflicts
with commit 6b914fc07ca8(octeontx2-af: Skip PFs if not enabled) from
marvell SDK11. When merged this into v5.15.112, we allocate bitmaps
using devm_kcalloc() and free bitmaps using bitmap_free(), this will
cause memory free error and the following panic, replace devm_kcalloc()
with bitmap_zalloc() to solve this problem.
