powerpc/ftrace: Fix nop of modules on 64bit LE (ABIv2)
There is a bug in the handling of the function entry when we are nopping
out a branch from a module in ftrace.
We compare the result of module_trampoline_target() with the value of
ppc_function_entry(), and expect them to be true. But they never will
be.
module_trampoline_target() will always return the global entry point of
the function, whereas ppc_function_entry() will always return the local.
Fix it by using the newly added ppc_global_function_entry().
