driver core: location: Free struct acpi_pld_info *pld before return false
[ Upstream commit 0d150f967e8410e1e6712484543eec709356a65d ]
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: bc443c31def5 ("driver core: location: Check for allocations failure")
