spi: fix parent-device reference leak

Fix parent-device reference leak due to SPI-core taking an unnecessary reference to the parent when allocating the master structure, a reference that was never released. Note that driver core takes its own reference to the parent when the master device is registered. Fixes: 49dce68 ("spi doesn't need class_device") Signed-off-by: Johan Hovold <[email protected]> Signed-off-by: Mark Brown <[email protected]> Cc: [email protected]
