p54usb: fix nasty use after free
In theory, the firmware acks the received a data frame, before signaling the driver to free it again.
However Artur Skawina <art.08.09@gmail.com> has shown that it can happen in reverse order as well.
This is very bad and could lead to memory corruptions, oopses and panics.
Thanks to Artur Skawina <art.08.09@gmail.com> for reporting and debugging this issue.
