[PATCH bpf-next] bpf: remove __btf_name_valid() and change to btf_name_valid_identifier()

[Jeongjun Park]

__btf_name_valid() can be completely replaced with 
btf_name_valid_identifier, and since most of the time you already call 
btf_name_valid_identifier instead of __btf_name_valid , it would be 
appropriate to rename the __btf_name_valid function to 
btf_name_valid_identifier and remove __btf_name_valid.
