IOMUX: Fix access past end of console_devices
We should only access console_devices[file][i] once we have checked that i
< cd_count[file]. Otherwise, we will access uninitialized memory at the end
of the loop. console_devices[file][i] should not be NULL, but putting the
assignment in the loop condition allows us to ensure that i is checked
beforehand. This isn't a bug, but it does make valgrind stop complaining.
