Zhenzhong Duan 8f23c0dcd0 spi: spidev: fix a potential use-after-free in spidev_release() 
[ Upstream commit 06096cc6c5a84ced929634b0d79376b94c65a4bd ]

If an spi device is unbounded from the driver before the release
process, there will be an NULL pointer reference when it's
referenced in spi_slave_abort().

Fix it by checking it's already freed before reference.
