Subject: [PATCH v2 1/5] sunrpc: simplify two-level sysctl registration for tsvcrdma_parm_table

From: Luis Chamberlain <[email-masked]>
Date: Sat, 11 Mar 2023 12:51:44 -0800

There is no need to declare two tables to just create directories,
this can be easily be done with a prefix path with register_sysctl().

Simplify this registration.
