cfg80211: remove superfluous !last_request check in reg_device_remove()
Commit 0ad8acaf "cfg80211: fix NULL pointer deference in reg_device_remove()" added a check that last_request is non-NULL, rendering the 2nd check superfluous. While there, rearrange the code a bit so it's a little more straight forward. Signed-off-by: Chris Wright <chrisw@sous-sol.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
