net: wwan: iosm: fix memory leak in ipc_pcie_read_bios_cfg

[ Upstream commit d38a648d2d6cc7bee11c6f533ff9426a00c2a74c ]

ipc_pcie_read_bios_cfg() is using the acpi_evaluate_dsm() to
obtain the wwan power state configuration from BIOS but is
not freeing the acpi_object. The acpi_evaluate_dsm() returned
acpi_object to be freed.

Free the acpi_object after use.
