mmc: sd: fix redundant 1.8V voltage switch on cold boot with UHS card
When a UHS card successfully negotiates 1.8V signaling during normal
initialization, the host voltage switch is performed as part of the
ACMD41 handshake. Without this fix, the warm-reboot recovery path
would fire again immediately after, switching the host voltage a
second time unnecessarily.
Add a check so the recovery path is only entered when the voltage
switch was not already performed during the current initialization
session.
