Josh Poimboeuf 98d0c8ebf7 x86/unwind/orc: Prevent unwinding before ORC initialization 
If the unwinder is called before the ORC data has been initialized,
orc_find() returns NULL, and it tries to fall back to using frame
pointers.  This can cause some unexpected warnings during boot.

Move the 'orc_init' check from orc_find() to __unwind_init(), so that it
doesn't even try to unwind from an uninitialized state.

Fixes: ee9f8fce99 ("x86/unwind: Add the ORC unwinder")
