From: Xiaoke Wang <xkernel.wang@xxxxxxxxxxx>
There is a memory allocation in _r8712_init_recv_priv(). Since the
original type of this function is void, now it is changed to int to
make the error of allocation failures propagate to its caller easily.
Signed-off-by: Xiaoke Wang <xkernel.wang@xxxxxxxxxxx>

ChangeLog:
v1->v2 remove kmemleak_not_leak().
