In order to support commands during data transfer, command and data handling needs to be untangled. That means sdhci_finish_cmd() must not be called from the data IRQ handler. It is being called because of busy signal handling, which is treating the command as not finished until the busy signal is released. Instead, move busy signal handling from sdhci_cmd_irq() into sdhci_finish_cmd(). Then the data IRQ handler does not need to call sdhci_finish_cmd() and can instead finish the request. What this means in practice for a command with busy signaling, is that the command response is read from the host controller when the command complete interrupt is received, thus freeing up the command circuit for other commands.
