Subject: [PATCH] ipmi_ssif: Fix uninitialized variable issue

Currently, function ssif_remove returns _rv_, which is a variable that
is never initialized.

Fix this by removing variable _rv_ and return 0 instead.

Addresses-Coverity-ID: 1467999 ("Uninitialized scalar variable")
Fixes: 6a0d23ed338e ("ipmi: ipmi_unregister_smi() cannot fail, have it
return void")
