[PATCH 02/15] perf jit: Remove some no-op error handling

[Arnaldo Carvalho de Melo <acme@kernel.org>]

From: Dan Carpenter <dan.carpenter@oracle.com>

The 'info.e_machine' struct member is an uint16_t so 'm' is never less
than zero.  It looks like this was maybe left over code from earlier
versions so I've just removed it.
