This fix allows connection of internal VLAN to the external TAP interface.
If tap_win32_write function always returns 0, the TAP network interface
in QEMU is disabled.

Compiling with GCC 4.6.0 20100925 produced warnings like:
/src/qemu/net/tap-win32.c: In function 'tap_win32_open':
/src/qemu/net/tap-win32.c:582:12: error: variable 'hThread' set but not used [-Werror=unused-but-set-variable]
Fix by removing the unused variables.

error_report() terminates the message with a newline. Strip it it
from its arguments.
This fixes a few error messages lacking a newline:
net_handle_fd_param()'s "No file descriptor named %s found", and
tap_open()'s "vnet_hdr=1 requested, but no kernel support for
IFF_VNET_HDR available" (all three versions).
There's one place that passes arguments without newlines
intentionally: load_vmstate(). Fix it up.
net_check_clients() prints this when an VLAN has host devices, but no
guest devices. It uses VLANState members nb_guest_devs and
nb_host_devs to keep track of these devices. However, -device does
not update nb_guest_devs, only net_init_nic() does that, for -net nic.
Check the VLAN clients directly, and remove the counters.
