Andrii Nakryiko 971fb5057d bpf: Fix missing -EFAULT return on user log buf error in btf_parse() 
btf_parse() is missing -EFAULT error return if log->ubuf was NULL-ed out
due to error while copying data into user-provided buffer. Add it, but
handle a special case of BPF_LOG_KERNEL in which log->ubuf is always NULL.
