packet, clang-tidy: Packet pool buffers are not NULL

struct pool always needs a non-NULL buf field: it points either to the
actual memory used to store packets, or for vhost-user to the vhost user
memory structure which will contain the packets.  We set this pointer
when we initialise the pool.  However, clang-tidy (as of 22.1.4, at least)
doesn't realise this in packet_check_range(), causing UB warnings due to
the subtraction of ptr and p->buf.

Clue it in with an assert().
