Subject: lib/oid_registry.c: remove redundant assignment to variable num
Date: Mon, 17 Oct 2022 22:45:56 +0100

The variable num is being assigned a value that is never read, it is being
re-assigned a new value in both paths if an if-statement.  The assignment
is redundant and can be removed.

Cleans up clang scan build warning:
lib/oid_registry.c:149:3: warning: Value stored to 'num' is
never read [deadcode.DeadStores]
