[PATCH] apci: apicinstance: clean up smatch warning

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

smatch gets confused by the use of count to check if the madt table
has been set and the code is a little bit clearer if we just check
to see if the table is not set by checking if it is NULL.
