[PATCH 3.16 063/192] libertas: Fix lbs_prb_rsp_limit_set()

[Ben Hutchings]

3.16.49-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

commit 69551f5f370cc20342fab17ca54716b6ec7e332d upstream.

The kstrtoul() test was reversed so this always returned -ENOTSUPP.

Fixes: 27d7f47756f4 ("net: wireless: replace strict_strtoul() with kstrtoul()")
