Subject: ftrace: Fix accounting bug with direct->count in
 register_ftrace_direct()
Patch-mainline: v5.5-rc1
Git-commit: 1c7f9b673dc0a15753274c4e7f5ebfd4468fc69f
References: bsc#1177028

The direct->count wasn't being updated properly, where it only was updated
when the first entry was added, but should be updated every time.

Fixes: 013bf0da04748 ("ftrace: Add ftrace_find_direct_func()")
