Subject: igc: Fix igc_uc_unsync()
Patch-mainline: v5.8-rc1
Git-commit: ec00f1090735259151568f6b74d19c3230d65787
References: jsc#SLE-13533

In case igc_del_mac_filter() returns error, that error is masked
since the functions always return 0 (success). This patch fixes
igc_uc_unsync() so it returns whatever value igc_del_mac_filter()
returns (0 on success, negative number on error).
