Jules Irenge dcce11d545 bpf: Add missing annotations for __bpf_prog_enter() and __bpf_prog_exit() ...

Sparse reports a warning at __bpf_prog_enter() and __bpf_prog_exit()

warning: context imbalance in __bpf_prog_enter() - wrong count at exit
warning: context imbalance in __bpf_prog_exit() - unexpected unlock

The root cause is the missing annotation at __bpf_prog_enter()
and __bpf_prog_exit()

Add the missing __acquires(RCU) annotation
Add the missing __releases(RCU) annotation
