packet: dont call sleeping functions while holding rcu_read_lock()
commit 654d1f8a019dfa06d (packet: less dev_put() calls)
introduced a problem, calling potentially sleeping functions from a
rcu_read_lock() protected section.
Fix this by releasing lock before the sock_wmalloc()/memcpy_fromiovec() calls.
After skb allocation and copy from user space, we redo device
lookup and appropriate tests.
