[PATCH] mmc: sdhci: Start status timeout after command issue

[Tanmay Kathpalia]

The status polling timeout in sdhci_send_command() should measure the
time spent waiting for the command interrupt after the command has been
issued.

Do not initialize the timer at function entry, since the command inhibit
wait and setup path can consume time before SDHCI_COMMAND is written.
Start the timer immediately after issuing the command instead.
