Josh Poimboeuf 082dc185b8 parisc/ftrace: Fix function graph tracing disablement
commit a5f05a138a8cac035bf9da9b6ed0e532bc7942c8 upstream.

Due to an apparent copy-paste bug, the parisc implementation of
ftrace_disable_ftrace_graph_caller() doesn't actually do anything.
It enables the (already-enabled) static key rather than disabling it.

The result is that after function graph tracing has been "disabled", any
subsequent (non-graph) function tracing will inadvertently also enable
the slow fgraph return address hijacking.

Fixes: 98f2926171 ("parisc/ftrace: use static key to enable/disable function graph tracer")
