qlcnic: Fix potential NULL dereference
[net-next:master 301/302] drivers/net/ethernet/qlogic/qlcnic/qlcnic_hw.c:563 qlcnic_set_multi() error: potential null dereference 'cur'. (kzalloc returns null) o Break out of the loop after memory allocation failure. Program all the MAC addresses that were cached in the return path.
