mmc: fix data timeout for SEND_EXT_CSD
Commit 0d3e0460f307e84904968aad6cff97bd688583d8
"MMC: CSD and CID timeout values" inadvertently broke
the timeout for the MMC command SEND_EXT_CSD.
This patch puts it back again.
Depending on the characteristics of the controller,
this bug may prevent the use of MMC cards.
