c3a9ad3117 ("oidset: add iterator methods to oidset", 2017-11-21)
introduced a 'oidset_init()' function in oidset.h, which has void as
return type, but returns an expression.
This makes the solaris compiler fail with:
"oidset.h", line 30: void function cannot return value
As the return type is void, and even the return type of the expression
we're trying to return (oidmap_init) is void just remove the return
statement to fix the compiler error.

/**

|
* This API is similar to sha1-array, in that it maintains a set of object ids
|
|
* in a memory-efficient way. The major differences are:
|
|
*
|
|
* 1. It uses a hash, so we can do online duplicate removal, rather than
|
|
* sort-and-uniq at the end. This can reduce memory footprint if you have
|
|
* a large list of oids with many duplicates.
|
|
*
|
|
* 2. The per-unique-oid memory footprint is slightly higher due to hash
|
|
* table overhead.
