bz 4a5ffff1ba Fix logic errors in iwm_pcie_load_firmware_chunk introduced in r314065.
* There's no reason to have a while() loop here, because:
    - if msleep returns 0, that means we were woken up by the interrupt handler,
      and we are going to exit immediately as sc_fw_chunk_done will now be 1
      (there is nothing else that sleeps on sc_fw.)
    - if msleep doesn't return 0 (i.e. it returned ETIMEDOUT) then we will
      exit immediately because of the if-test.
   So, just use a single msleep() and then check sc_fw_chunk_done as before.
 * The comment said we were sleeping for 5 seconds, but the msleep was only
   for 1. Before r314065, this was 1 second and so was the comment,
   and in that commit the comment was changed and the function call wasn't.

Possibly fixes failures to initialize uCode on certain devices.
