pcmcia: deprecate CS_NO_MORE_ITEMS

CS_NO_MORE_ITEMS is returned by the CIS tuple reading and parsing code if
the end of a tuple chain is reached. As at least one PCMCIA driver relies
on matching this return value, replace it with -ENOSPC which is now
uniquely used for this purpose within the in-kernel pcmcia subsystem.
