tcp_vu: head_cnt need not be global

head_cnt is a global variable which tracks how many entries in head[] are
currently used.  The fact that it's global obscures the fact that the
lifetime over which it has a meaningful value is quite short: a single
call to of tcp_vu_data_from_sock().

Make it a local to tcp_vu_data_from_sock() to make that lifetime clearer.
We keep the head[] array global for now - although technically it has the
same valid lifetime - because it's large enough we might not want to put
it on the stack.
