Subject: RDMA/netlink: Add __maybe_unused to static inline in C file
Patch-mainline: v5.16-rc2
Git-commit: 83dde7498fefeb920b1def317421262317d178e5
References: bsc#1046306 FATE#322942

Like other commits in the tree add __maybe_unused to a static inline in a
C file because some clang compilers will complain about unused code:

>> drivers/infiniband/core/nldev.c:2543:1: warning: unused function '__chk_RDMA_NL_NLDEV'
   MODULE_ALIAS_RDMA_NETLINK(RDMA_NL_NLDEV, 5);
   ^

Fixes: e3bf14bdc17a ("rdma: Autoload netlink client modules")
