ACPI: HMAT: remove unnecessary variable initialization
[ Upstream commit 14f16d47561ba9249efc6c2db9d47ed56841f070 ]
In hmat_register_target_initiators(), the variable 'best' gets
initialized in the outer per-locality-type for loop. The initialization
just before setting up 'Access 1' targets was unnecessary. Remove it.
