x86/error_inject: Make just_return_func() globally visible
With link time optimizations enabled, I get a link failure:
./ccLbOEHX.ltrans19.ltrans.o: In function `override_function_with_return':
<artificial>:(.text+0x7f3): undefined reference to `just_return_func'
Marking the symbol .globl makes it work as expected.
