perf llvm: Return -ENOMEM when asprintf() fails

Zhihao sent a patch but it made llvm__compile_bpf() return what
asprintf() returns on error, which is just -1, but since this function
returns -errno, fix it by returning -ENOMEM for this case instead.

Fixes: cb76371441d098 ("perf llvm: Allow passing options to llc ...")
Fixes: 5eab5a7ee032ac ("perf llvm: Display eBPF compiling command ...")
