kprobes/x86: Remove IRQ disabling from jprobe handlers

Jprobes actually don't need to disable IRQs while calling
handlers, because of how we specify the kernel interface in
Documentation/kprobes.txt:

-----
 Probe handlers are run with preemption disabled.  Depending on the
 architecture and optimization state, handlers may also run with
 interrupts disabled (e.g., kretprobe handlers and optimized kprobe
 handlers run without interrupt disabled on x86/x86-64).
-----

So let's remove IRQ disabling from jprobes too.
