wifi: wl3501_cs: Fix an error handling path in wl3501_probe()

[ Upstream commit 391af06a02e7642039ac5f6c4b2c034ab0992b5d ]

Should wl3501_config() fail, some resources need to be released as already
done in the remove function.

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