net: hns3: do mac configuration instead of rollback when malloc mac node fail

driver inclusion
category: bugfix
bugzilla: NA
CVE: NA

--------------------------------------------

Currently, when traversing the mac list, and allocating memory
fail for mac node, it will stop traversing, and rollback the
tmp_add_list and tmp_del_list. It's unnecessary, we can continue
the configuration with the tmp_add_list and tmp_del_list, which
may free some memory after delete node.
