ftrace: Rename ftrace_ops field from trampolines to nr_trampolines
Having two fields within the same struct that is off by one character can be confusing and error prone. Rename the counter "trampolines" to "nr_trampolines" to explicitly show it is a counter and not to be confused by the "trampoline" field.
