Subject: [PATCH 1/2] staging: r8188eu: call _cancel_timer_ex from _rtw_free_recv_priv

The _rtw_init_recv_priv() initializes precvpriv->signal_stat_timer and
sets it's timeout interval to 1000 ms. But _rtw_free_recv_priv()
doesn't cancel the timer and we need to explicitly call
_cancel_timer_ex() after we call _rtw_free_recv_priv() to cancel the
timer.
Call _cancel_timer_ex() from inside _rtw_free_recv_priv() as every init
function needs a matching free function.
