Subject: [PATCH] pcmcia/electra_cf: Fix some return values in 'electra_cf_probe()' in case of error

'status' is known to be 0 at this point. It must be set to a meaningful
value in order to return an error code if one of the 'of_get_property()'
call fails.

Return -EINVAL in such a case.

Fixes: 2b571a066a2f("pcmcia: CompactFlash driver for PA Semi Electra boards")
