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. Signed-off-by: Adrian Hunter <adrian.hunter@nokia.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
