[PATCH wireless] orinoco: Fix an error handling path in spectrum_cs_probe()

[Christophe JAILLET]

Should spectrum_cs_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
spectrum_cs_probe(), not spectrum_cs_attach().
