Recent change to use cpuhp_setup_state_cpuslocked() with commit
fe2a5cd8aa03 ("ARM/hw_breakpoint: Use cpuhp_setup_state_cpuslocked()")
missed to change the related paired cpuhp_remove_state_nocalls_cpuslocked().
Now if arch_hw_breakpoint_init() fails, we get "WARNING: possible recursive
locking detected" on the exit path.
Fixes: fe2a5cd8aa03 ("ARM/hw_breakpoint: Use
cpuhp_setup_state_cpuslocked()")
