[ Upstream commit 83cd92b46484aa8f64cdc0bff8ac6940d1f78519 ]
When initializing the __param array with a one liner, if all args are
const, the initial array value will be placed in the rodata section but
because libbpf does not support relocation in the rodata section, any
pointer in this array will stay NULL.
Fixes: c09add2fbc ("tools/libbpf: Add bpf_iter support")
