Fix nomenclature for USB and PCI wireless devices

A mouse that uses a USB connection is called a "USB mouse" device (or
"USB mouse" for short), not a "mouse USB" device. By analogy, a WiFi
adapter that connects to the host computer via USB is a "USB wireless"
device, not a "wireless USB" device. (The latter term more properly
refers to a defunct Wireless USB specification, which described a
technology for sending USB protocol messages over an ultra wideband
radio link.)

Similarly for a WiFi adapter card that plugs into a PCIe slot: It is a
"PCIe wireless" device, not a "wireless PCIe" device.

Rephrase the text in the kernel source where the word ordering is
wrong.
