[PATCH 3/4] sparc: bpf_jit: Avoid assignment for "flen" if BPF JIT is disabled

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Sat, 3 Sep 2016 18:00:03 +0200

Move the assignment for the local variable "flen" a bit at the beginning
so that it will only be performed if BPF JIT is enabled for this function.
