linux-usb:usb-storage fails to attach to Huawei Datacard cdrom device, fix kernel 2.6.31-rc4

From: fangxiaozhi <[email protected]>
1. This patch is based on the kernel of 2.6.31-rc4
2. In this patch, we always make the return value of function usb_stor_huawei_e220_init to be zero. Then it will not prevent usb-storage driver from attaching to the CDROM device of Huawei Datacard.
