init_wifidev() & setup_proc_entry() can also fail in _init_airo_card().

This adds the checks & cleanup code and removes some whitespace.

NAK: create_proc_entry() is complicated. You are correct it can fail -- but to add to the confusion, when CONFIG_PROC_FS is disabled, the wrapper will also return NULL -- which is NOT a failure case.
