ftrace: check for failure for all conversions
commit 3279ba37db5d65c4ab0dcdee3b211ccb85bb563f upstream.
Due to legacy code from back when the dynamic tracer used a daemon,
only core kernel code was checking for failures. This is no longer
the case. We must check for failures any time we perform text modifications.
