Arnaldo Carvalho de Melo 8ff266de89 perf llvm: Return -ENOMEM when asprintf() fails
[ Upstream commit c435c166dcf526ac827bc964d82cc0d5e7a1fd0b ]

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: cb76371441 ("perf llvm: Allow passing options to llc ...")
Fixes: 5eab5a7ee0 ("perf llvm: Display eBPF compiling command ...")
