kprobes/x86: Fix kprobe-booster not to boost far call instructions
Fix the kprobe-booster not to boost far call instruction,
because a call may store the address in the single-step
execution buffer to the stack, which should be modified
after single stepping.
Currently, this instruction will be filtered as not
boostable in resume_execution(), so this is not a
critical issue.
