Subject: [PATCH 2/2] staging: rtl8188eu: odm: conditional setting with no effect

The if and the else branch code are identical - so the condition has no
effect on the effective code - this patch removes the condition and the
duplicated code. Due to this being a fall-through-if here - the first
if condition has no effect either - so it also can be removed. 
struct mlme_priv is thus also no longer needed here.

Signed-off-by: Nicholas Mc Guire <hofrat@...dl.org>
---

The if/else executes the same code in both branches so the
condition has no effect.

This needs a check by someone who knows the details of the driver
as it could be that the two branches actually should be different.
>From the comments it seems that an effect is actually intended so this
may be a bug.

The comment was updated to reflect the changes

Patch was only compile-tested for x86_64_defconfig + CONFIG_STAGING=y
CONFIG_R8188EU=m

Patch is against 3.19.0-rc7 (localversion-next is -next-20150204)
