[PATCH] bpf: use the expected instruction for NOPs

Hi David,

Just an aside - wouldn't it be a good idea if the ISA did define an explicit
encoding for no-ops ?

Thanks for pointing this out.  I took the original encoding from the
gas/testsuite/gas/all/org-1.s file, in the hopes that it would be correct
one.

Approved and applied.
