You have transformed this faithfully, but my instinct says that the
original code is wrong.  It should be:

	if (!precvbuf->reuse || !precvbuf->pskb) {

I checked and usb_read_port() is implemented this way in
drivers/staging/rtl8188eu/os_dep/usb_ops_linux.c.  Again I am going on
instinct and not a full understanding of the code, but I'm probably
correct.

Anyway, this is not related to the patch so we should fix it in a later
patch, but let's not forget.

TODO: rtl8712: fix a reversed condition in r8712_usb_read_port()
