powerpc64/modules: correctly iterate over stubs in setup_ftrace_ool_stubs

Browse Source 
CONFIG_PPC_FTRACE_OUT_OF_LINE introduced setup_ftrace_ool_stubs() to
extend the ppc64le module .stubs section with an array of
ftrace_ool_stub structures for each patchable function.

Fix its ppc64_stub_entry stub reservation loop to properly write across
all of the num_stubs used and not just the first entry.
