net: Reexport sock_alloc_send_pskb 

The function sock_alloc_send_pskb is completely useless if not
exported since most of the code in it won't be used as is.  In
fact, this code has already been duplicated in the tun driver.

Now that we need accounting in the tun driver, we can in fact
use this function as is.  So this patch marks it for export again.
