MFC 240692,241228:
Adjust the ioctl workaround from r234501:
- Ensure the native ioctl path always allocates a 4kb buffer if a request
  uses a buffer size of 0.
- Rounding all small requests up to 32k swamped the controller causing
  firmware hangs.  Instead, round requests smaller than 64k up to the next
  power of 2 as a general rule.  To handle the one known special case of a
  command that accepts a 12k buffer returning a 24k-ish reply, round
  requests between 8k and 16k up to 32k rather than 16k.  The result is
  that commands less than 8k should now be rounded up to a smaller size
  (either 4k or 8k) rather than 32k.
