Subject: [PATCH] ftrace: Remove unused list 'ftrace_direct_funcs'

From: "Dr. David Alan Gilbert" <[email protected]>

Commit 8788ca164eb4b ("ftrace: Remove the legacy _ftrace_direct API")
stopped using 'ftrace_direct_funcs' (and the associated
struct ftrace_direct_func). Remove them.

Build tested only (on x86-64 with FTRACE and DYNAMIC_FTRACE
enabled)
