bpf: Use stack id functions instead of __bpf_get_stackid

Browse source

Replacing __bpf_get_stackid calls with sequence of following functions:

  stackid_fastpath
  stackid_new_bucket
  stackid_install

This makes code more structured and allows us to easily disable
preemption only in bpf_get_stackid in following changes.
