drivers/leds/leds-tca6507.c: cleanup error handling in tca6507_probe()
Just a small tidy-up.
1) There is a NULL dereference if the tca allocation fails.
2) The call to cancel_work_sync() isn't needed because we haven't
scheduled any work.
3) The call to i2c_set_clientdata() isn't needed because the core
handles that automatically if probe() fails.
4) I added some curly braces for style reasons.
