[PATCH 4.9 107/175] usb: oxu210hp-hcd: Fix memory leak in oxu_create

[Greg Kroah-Hartman]

From: Zhang Qilong <zhangqilong3@xxxxxxxxxx>

[ Upstream commit e5548b05631ec3e6bfdaef1cad28c799545b791b ]

usb_create_hcd will alloc memory for hcd, and we should
call usb_put_hcd to free it when adding fails to prevent
memory leak.
