pf isn't being assigned. Clang reports:

+../drivers/net/ethernet/intel/ice/ice_lag.c:657:22: warning: variable 
'pf' is uninitialized when used here [-Wuninitialized]
+                ice_clear_rdma_cap(pf);
+                                   ^~
+../drivers/net/ethernet/intel/ice/ice_lag.c:648:19: note: initialize

+        struct ice_pf *pf;
+                         ^
+                          = NULL
+1 warning generated.
