Alexei Starovoitov c9a8a448e5 bpf: Fix subprog names in stack traces. 
[ Upstream commit 9c7c48d6a1e2eb5192ad5294c1c4dbd42a88e88b ]

The commit 7337224fc150 ("bpf: Improve the info.func_info and info.func_info_rec_size behavior")
accidently made bpf_prog_ksym_set_name() conservative for bpf subprograms.
Fixed it so instead of "bpf_prog_tag_F" the stack traces print "bpf_prog_tag_full_subprog_name".

Fixes: 7337224fc150 ("bpf: Improve the info.func_info and info.func_info_rec_size behavior")
