Subject: [PATCH v2 10/16] mmc: sdhci: Fix to use data_timer only for data line commands

commit d7422fb489eee5587d3eec ("mmc: sdhci: Separate timer timeout for
command and data requests") while separating timer timeout for
command and data requests, passed cmd->mrq to sdhci_mod_timer (cmd is an
argument to sdhci_send_command) and in sdhci_mod_timer used mrq->cmd
to check if it is a data line command. This results in using
data timer for commands like MMC_SET_BLOCK_COUNT (CMD23) though it is
not a data line command. Fix it here.

Fixes: commit d7422fb489eee5587d3eec ("mmc: sdhci: Separate timer timeout for
command and data requests")
