Igor Ostapenko 18fb9174cd netlink: fix snl_writer and linear_buffer re-allocation logic 
- Use the correct base pointer after re-allocation to avoid buffer
  overflows.

- Maintain correct snl_writer.size, which avoids redundant memory
  allocation, e.g. a need for ~1k bytes may end up with ~32k
  linear_buffer actually allocated.

This fixes a pfctl regression at least for armv7 after the addrule logic
migration to netlink:
  ffbf25951e7b ("pf: convert rule addition to netlink")

The add rule command creates a bigger than default size netlink requests
which triggers the re-allocation logic.
