USB SL811HS HCD: Fix memory leak in sl811h_urb_enqueue()

Browse Source 
In drivers/usb/host/sl811-hcd.c::sl811h_urb_enqueue(), memory is allocated
with kzalloc() and assigned to 'ep'. If we leave via the 'fail' label due
to 'if (ep->maxpacket > H_MAXPACKET)', then 'ep' will go out of scope
without having been assigned to anything, so we'll leak the memory we
allocated.
This patch fixes the leak by simply calling kfree(ep); before jumping to
the 'fail' label.
