powerpc/ftrace: ensure ftrace record ops are always set for NOPs

Browse source

[ Upstream commit 5337609a31 ]

When an ftrace call site is converted to a NOP, its corresponding
dyn_ftrace record should have its ftrace_ops pointer set to
ftrace_nop_ops.

Correct the powerpc implementation to ensure the
ftrace_rec_set_nop_ops() helper is called on all successful NOP
initialization paths. This ensures all ftrace records are consistent
before being handled by the ftrace core.
