Greg Kroah-Hartman dbafc28955 NFC: pn533: don't send USB data off of the stack
It's amazing that this driver ever worked, but now that x86 doesn't
allow USB data to be sent off of the stack, it really does not work at
all.  Fix this up by properly allocating the data for the small
"commands" that get sent to the device off of the stack.

We do this for one command by having a whole urb just for ack messages,
as they can be submitted in interrupt context, so we can not use
usb_bulk_msg().  But the poweron command can sleep (and does), so use
usb_bulk_msg() for that transfer.
