Subject: [PATCH 14/16] staging: wfx: simplify wfx_remove_interface()

From: Jérôme Pouiller <jerome.pouiller@...abs.com>

In wfx_remove_interface(), the current code differentiate AP and Station
cases. However, it is not necessary. In all cases, the only important
thing is the call to hif_reset(). We can use the same code to support
all cases.
