bpf: Remove static qualifier from local subprog pointer

Browse source

The local subprog pointer in create_jt() and visit_abnormal_return_insn()
was declared static.

It is unconditionally assigned via bpf_find_containing_subprog() before
every use. Thus, the static qualifier serves no purpose and rather creates
confusion. Just remove it.

Fixes: e40f5a6bf8 ("bpf: correct stack liveness for tail calls")
Fixes: 493d9e0d60 ("bpf, x86: add support for indirect jumps")
