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: 49dce689ad4e ("spi doesn't need class_device")
Cc: stable <stable@vger.kernel.org>	# v2.6.24
