x86/orc: Make the is_callthunk() definition depend on CONFIG_BPF_JIT=y
Recent commit:
020126239b8f Revert "x86/orc: Make it callthunk aware"
Made the only user of is_callthunk() depend on CONFIG_BPF_JIT=y, while
the definition of the helper function is unconditional.
Move is_callthunk() inside the #ifdef block.
Addresses this build failure:
arch/x86/kernel/callthunks.c:296:13: error: ‘is_callthunk’ defined but not used [-Werror=unused-function]
