staging: r8188eu: handle errors from ReadAdapterInfo8188EU

Update ReadAdapterInfo8188EU to return 0 for success or a negative
error code. If rtw_read8 fails, we can just relay the error it returns.

Update rtw_usb_if1_init to check the return value from
ReadAdapterInfo8188EU. For now, rtw_usb_if1_init does not yet pass errors
from ReadAdapterInfo8188EU on to its caller.
