[PATCH -next] staging: wlags49_h2: fix error return code in wl_adapter_insert()

[Wei Yongjun]

From: Wei Yongjun <yongjun_wei at trendmicro.com.cn>

When return from wl_adapter_insert() in the register_netdev() error
handling case, 'ret' which is 0 is returned, but we should return a
negative error code instead, so fix to return the return value of
register_netdev().

Introduce by commit 657d4c86d4cd85a4696445f6fb2fe0941a5724ff
