CHROMIUM: iwl7000: sdio: avoid read/write operations if the bus is dead
Recovery takes too much time if the bus is dead (each timeout
is 2000ms, etc.).
try avoiding it by setting a flag when the bus is dead, and avoid
any bus access until recovery.
There still might be significant delays caused by implicit
mmc access (e.g. sdio_disable_func()), but at least avoid
the direct read/write operations.
Additionally, explicitly skip fw dump in this case, as it will
result in garbage data (and might take signifcant time)
