driver core: location: Free struct acpi_pld_info *pld before return false 

[ Upstream commit 0d150f967e ]

struct acpi_pld_info *pld should be freed before the return of allocation
failure, to prevent memory leak, add the ACPI_FREE() to fix it.

Fixes: bc443c31de ("driver core: location: Check for allocations failure")
