orinoco: Move context allocation after processing the skb

[ Upstream commit a31eb615646a63370aa1da1053c45439c7653d83 ]

ezusb_xmit() allocates a context which is leaked if
orinoco_process_xmit_skb() returns an error.

Move ezusb_alloc_ctx() after the invocation of
orinoco_process_xmit_skb() because the context is not needed so early.
ezusb_access_ltv() will cleanup the context in case of an error.

Fixes: bac6fafd ("orinoco: refactor xmit path")
