Palmer Dabbelt 66d987b80d RISC-V: Take text_mutex in ftrace_init_nop() 
[ Upstream commit 66d18dbda8 ]

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.
