[PATCH 2/2] mci-bcm2835: Fix return type handling of bcm2835_mci_wait_command_done()

[Uwe Kleine-König]

The function returns a negative value in a code path and the return value
is used as a return value for another functions returning int, too. So
change the value to int (and the variable holding the return value, too).
