[PATCH] rtlwifi: rtl8192ee: Remove redundant initialization of variable version

[Colin King]

From: Colin Ian King <colin.king@canonical.com>

The variable version is being initialized with a value that is
never read, it is being updated afterwards in both branches of
an if statement. The assignment is redundant and can be removed.

Addresses-Coverity: ("Unused value")
