[RFC PATCH 01/10] hw/sd: When card is in wrong state, log which state it is

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

We report the card is in an inconsistent state, but don't precise
in which state it is. Add this information, as it is useful when
debugging problems.

Since we will reuse this code, extract as sd_invalid_state_for_cmd()
helper.
