Subject: [PATCH] checkpatch: Remove migrated RCU APIs from deprecated_apis

The deprecated_apis map was created in [1] so checkpatch would flag
deprecated RCU APIs. These deprecated APIs have since been removed from the
kernel. This patch removes them from this map so checkpatch doesn't waste
time looking for them, and so readers of checkpatch looking for deprecated
APIs don't waste time searching for them.
