bpf: Remove unnecessary err < 0 check in bpf_struct_ops_map_update_elem

Browse source

There is a "if (err)" check earlier, so the "if (err < 0)"
check that this patch removing is unnecessary. It was my overlook
when making adjustments to the bpf_struct_ops_prepare_trampoline()
such that the caller does not have to worry about the new page when
the function returns error.

Fixes: 187e2af05a ("bpf: struct_ops supports more than one page for trampolines.")
