spi: spidev: remove debug messages that access spidev->spi without locking

Browse source

[ Upstream commit 6b35b173db ]

The two debug messages in spidev_open() dereference spidev->spi without
taking the lock and without checking if it's not null. This can lead to
a crash. Drop the messages as they're not needed - the user-space will
get informed about ENOMEM with the syscall return value.
