[PATCH] pcmcia: pcmcia_resource: return 0 if success

[Jason Wang]

The initial value of variable `ret' is -EINVAL, which is used for
returning the error status in `pcmcia_release_io' when errors occur.
But if there is no error in `pcmcia_release_io', `ret' should be changed
to a successful value to return. Thus we change `ret' value to 0 when
the function's status is successful.
