[PATCH v2 3/3] staging: rtl8712: add two validation check in r8712_init_drv_sw()

[xkernel . wang]

From: Xiaoke Wang <xkernel.wang@xxxxxxxxxxx>

_r8712_init_xmit_priv() or _r8712_init_recv_priv() returns -ENOMEM
when some allocations inside it failed.
So it is better to check the return status of them.
