RISC-V: Take text_mutex in ftrace_init_nop()
[ Upstream commit 66d18dbda8469a944dfec6c49d26d5946efba218 ]
Without this we get lockdep failures. They're spurious failures as SMP isn't
up when ftrace_init_nop() is called. As far as I can tell the easiest fix is
to just take the lock, which also seems like the safest fix.
