ACPI: Fix memory leak in acpi_bind_one()
Memory is allocated with kzalloc() and assigned to
'physical_node'. Then 'physical_node->node_id' is initialized with a
call to 'find_first_zero_bit()', if that results in a value greater
than ACPI_MAX_PHYSICAL_NODE we'll end up jumping to the 'err:' label
and there leave the function and let 'physical_node' go out of scope
and leak the memory we allocated.
This patch fixes the leak by simply freeing the unused/unneeded memory
pointed to by 'physical_node' just before we jump to 'err:'.
[rjw: The problem has been introduced by commit 1033f90 (ACPI: Allow
ACPI binding with USB-3.0 hub), which is new in 3.7-rc.]
