[PATCH] mwifiex: Remove redundant assignment

[PATCH] mwifiex: Remove redundant assignment

[zuoqilin1]

From: zuoqilin <zuoqilin@yulong.com>

There is no need to define the err variable,
and then assign -EINVAL, we can directly return -EINVAL.

We need to return 0 in success case. So this can't be removed.
