Subject: [PATCH] orinoco_usb: potential null dereference

Smatch complains that "upriv->read_urb" gets dereferenced before
checking for NULL.  It turns out that it's possible for
"upriv->read_urb" to be NULL so I added checks around the dereferences.

Also I remove an "if (upriv->bap_buf != NULL)" check because
"kfree(NULL) is OK.
