[PATCH wireless] ray_cs: Fix an error handling path in ray_probe()

[Christophe JAILLET]

Should ray_config() fail, some resources need to be released as already
done in the remove function.

While at it, remove a useless and erroneous comment. The probe is
ray_probe(), not ray_attach().

Fixes: 15b99ac17295 ("[PATCH] pcmcia: add return value to _config() functions")
