[PATCH v2 2/3] staging: rtl8712: change the type of _r8712_init_recv_priv()

[xkernel . wang]

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().
