Subject: rt2x00usb: Fix error return code
From: Christophe Jaillet <christophe.jaillet@xxxxxxxxxx>
commit 410280bac6224e066f4cf0b87db08f0418a135b6 upstream.
We know that 'retval = 0' because it has been tested a few lines above.
So, if 'devm_kmalloc' fails, 0 will be returned instead of an error code.
Return -ENOMEM instead.
Fixes: 8b4c0009313f ("rt2x00usb: Use usb anchor to manage URB")
