Subject: [PATCH v2] octeontx2-pf: Add error log forcn10k_map_unmap_rq_policer()

The cn10k_free_matchall_ipolicer() calls the cn10k_map_unmap_rq_policer()
for each queue in a for loop without checking for any errors.

Check the return value of the cn10k_map_unmap_rq_policer() function during
each loop, and report a warning if the function fails.
