Tao Chen f059795ec6 bpf: Remove migrate_disable in kprobe_multi_link_prog_run 
[ Upstream commit abdaf49be5 ]

Graph tracer framework ensures we won't migrate, kprobe_multi_link_prog_run
called all the way from graph tracer, which disables preemption in
function_graph_enter_regs, as Jiri and Yonghong suggested, there is no
need to use migrate_disable. As a result, some overhead may will be reduced.
And add cant_sleep check for __this_cpu_inc_return.

Fixes: 0dcac27254 ("bpf: Add multi kprobe link")
